Secret world seeds

Secret world seeds are world seeds which have been discovered as secret that generate worlds with strange or unique features. Unlike regular world seeds, which affect only the usual world structure, secret seeds can produce worlds with characteristics that would not be attainable through normal world generation, i.e., they can affect the game's mechanics while playing in that world. For instance, they may change enemy statistics and behavior, item drops, graphics, theme music and more.

Secret seeds use unique world-generating mechanics that differ from normal seeds. Using a secret seed overrides the normal use of seeds as a source of randomness and two worlds created via the same secret seed will not necessarily be identical.

There are currently four /  three different secret seeds.

Drunk world



 * Seeds:

This seed references the date of 1.4's official release (May 16, 2020) and invokes a highly extraordinary world generation referred to in the source code as drunkWorldGen. It has therefore come to be referred to by the Terraria community as drunk world. This seed celebrates Terraria's 9th birthday.


 * The Party Girl replaces the Guide upon entering the world for the first time.
 * Visiting this world once permanently unlocks a "Music" option in the Party Girl's menu, to toggle the game's default soundtrack for the Terraria: Otherworld soundtrack. Once unlocked, the option carries to all players and all worlds. Every song in Terraria's soundtrack is replaced with an Otherworld equivalent. In multiplayer, only players who unlocked the "Music" option themselves will hear the change.
 * Both ore variants for each tier generate, instead of just one (e.g. both Copper and Tin instead of only one of them).
 * This applies to Hardmode ores as well: It requires destroying six Demon or Crimson Altars for all ores instead of three. Destroying the first three altars will generate Hardmode ores as normal and destroying the next three altars will generate the other variants. Destroying more altars will repeat the cycle, generating more veins of those ores.
 * It is determined upon loading the world whether Silver or Tungsten Bullets are sold by the Arms Dealer and dropped from Pots. If the number of all placed tiles of Silver Ore in the world exceeds that of placed Tungsten Ore, then Silver Bullets will be sold and dropped, and vice versa (if the numbers are equal, Tungsten Bullets will be sold and dropped). This is not updated while playing in the world; the world will need to be exited and re-entered to refresh the information.
 * It is not known where it is decided for a Drunk World whether the Guide's following quotes reference Adamantite or Titanium:
 * Living Mahogany Trees can generate anywhere underground, not just in the Jungle.
 * The normally unobtainable items Moon Lord Legs and Red Potion can generate in Chests with a and  chance to appear, respectively.
 * Marble and Granite Caves swap their generation style.
 * The Underground Desert can generate on either side of the world, making it possible for the Underground Desert, Snow and Jungle biomes to all be on the same half of the map.
 * Bee Hives are larger, have elevated spawn rates that match Blood Moons and contain multiple Larvae.
 * The Underworld's horizontal layout is inverted, with the middle third as a continuous lava lake and the two thirds at the edges containing Ruined Houses. The generation of the houses are noticeably flawed and glitchy, with houses clipping into each other or spawning with incorrect dimensions.
 * Both Oceans always generate with an Ocean Cave, which normally has just a chance.
 * Gem trees and Underground Living Mahogany Trees are much more common.
 * Glowing moss biomes now have a chance to generate below the spawn area in the Cavern layer.
 * Scaled-up enemies are slightly larger and scaled-down enemies are slightly smaller (e.g. Little Eater of Souls and Big Eater of Souls).
 * Glowing moss biomes now have a chance to generate below the spawn area in the Cavern layer.
 * Scaled-up enemies are slightly larger and scaled-down enemies are slightly smaller (e.g. Little Eater of Souls and Big Eater of Souls).

Surface

 * The surface layer is slightly thicker, with the underground starting slightly lower than normal, relative to map height.
 * Living Trees generate much more frequently and may be clustered and interconnected underground.
 * The chance for a vanity tree to replace a forest tree during world generation is increased from to.
 * Deserts have a much higher chance of generating with a Pyramid.
 * Cactus plants placed during world generation have a chance to be larger than usual.
 * Floating Islands are now either Deserts with sand instead of dirt and/or Snow biomes with snow instead of dirt, with a corresponding Water Fountain. Snow islands even have Snow Clouds in place of Rain Clouds.
 * The Jungle generates without a tunnel to the surface.
 * The Jungle and the Snow biome generate on the same side opposite of the Dungeon.

Evil biomes

 * A single world will incorporate elements of both evil biomes during generation:
 * Both evil biomes generate, each on opposite sides of the world.
 * Both the Corruption and Crimson Biome Chests are present in the Dungeon.
 * Shadow Orbs and Crimson Hearts share a single counter. Only the first of either will be a guaranteed firearm and every third total will spawn its boss.
 * Both Demon Altars and Crimson Altars appear in their respective chasms.
 * However, only one type of altar will generate in the world outside of their chasms, regardless of the biome where they appear. The type of altar depends on which world evil is chosen when creating the world.
 * Crimtane Ore and Demonite Ore can both be found underground, one slightly more commonly than the other.


 * The world icon in the world selection menu shows a tree infected with both world evils.
 * The chosen world evil in the world creation menu will be the "main" world evil on the first day. Each dawn, the "main" world evil, used for processing otherwise permanent world-specific evil biome related mechanics, switches. This will impact the following mechanics:
 * Which items NPCs sell:
 * Corrupt or Crimson Seeds from the Dryad.
 * Vile or Vicious Powder from the Dryad.
 * Corrupt or Crimson Grass Wall from the Dryad.
 * The style of Deathweed Planter Box from the Dryad.
 * Purple or Red Solution from the Steampunker.
 * Decay Chamber or Flesh Cloning Vat from the Steampunker.
 * Which evil Biome Mimic can be spawned by the player.
 * The drops from the Eye of Cthulhu.
 * Which evil biome will be generated alongside the Hallow when the world transitions to Hardmode.
 * It is not known if the following are affected by the world evil switching:
 * What type of evil Goldfish, Bunnies and Penguins become during a Blood Moon.
 * Evil biome-specific quests given by the Angler.
 * Biome specific quotes from NPCs:
 * Guide
 * Demolitionist
 * Dryad
 * What type of brick is generated by the defeated Wall of Flesh.
 * What type of block a random piece of stone is sometimes converted to when an altar is broken.
 * What type of evil related ore generates more commonly.
 * Demolitionist
 * Dryad
 * What type of brick is generated by the defeated Wall of Flesh.
 * What type of block a random piece of stone is sometimes converted to when an altar is broken.
 * What type of evil related ore generates more commonly.
 * Demolitionist
 * Dryad
 * What type of brick is generated by the defeated Wall of Flesh.
 * What type of block a random piece of stone is sometimes converted to when an altar is broken.
 * What type of evil related ore generates more commonly.
 * Demolitionist

 * What type of brick is generated by the defeated Wall of Flesh.
 * What type of block a random piece of stone is sometimes converted to when an altar is broken.
 * What type of evil related ore generates more commonly.
 * What type of evil related ore generates more commonly.

Dungeon and Jungle Temple

 * Both the Dungeon and the Jungle Temple are painted brown, deep sky blue, green, lime, purple, red, or yellow; and both feature spikes that extend three blocks high instead of two.
 * The surface entrance to the Dungeon is completely removed. The Dungeon instead generates underneath a "dead" Living Tree, with leaves painted brown to differentiate it from other Living Trees.
 * The Old Man is placed in a pre-generated house underground in the Dungeon, making it harder to fight Skeletron.
 * Since the Dungeon point (the leftmost of the two tiles that the Old Man stands on at night) is located inside the Old Man's underground house, the Cultists also spawn in there.
 * More of the Dungeon depth can be traversed without spawning Dungeon Guardians, but going below a depth of 40 tiles below the Dungeon point will still spawn them.
 * This makes it possible to obtain a Water Bolt as well as encounter the Bound Mechanic prior to defeating Skeletron.
 * Furthermore, a locked Gold Chest is almost always generated in the entrance room and it will always contain a Muramasa. This is not unique to the drunk world seed, but is an artifact of the way that Dungeon loot is generated (see Dungeon § Notes for more details).

Unaffected world generation aspects
While Drunk World generation generally causes otherwise per-world counterparts to coexist upon generation or through other methods, there remain some generation aspects that appear to be unaffected:
 * As mentioned previously, altar generation outside of chasms will always correspond to one world evil, rather than both generating as one would expect.
 * Not all types of moss will generate in the same world.

While generating

 * Generation descriptions and tips become random numbers that change every tick (except when "").
 * The background shows a Glowing Mushroom biome, with clouds that resemble Redigit's head. The moon moves backwards and resembles a smiley face, which was rumoured to happen in the real world on the same day as 1.4's release. Once the world finishes generating, it is possible to go back to the main menu with these effects still visible.
 * The outline of the progress bar rapidly flashes between Corruption and Crimson.
 * The Console Title music plays, instead of the normal Title Screen theme.
 * The Terraria logo spins out and disappears along with the version number.

Not the bees



 * Seeds (case-insensitive):

This seed references the NOT THE BEES! meme which originated from the 2006 horror film . It generates a world dominated by bee-themed biomes and bee-related items and structures.


 * Most of the world is replaced with the Jungle biome, with Hive and Honey Blocks found in abundance. See below for a full list of replaced tiles.
 * As a result, the player will spawn in the Jungle biome, as opposed to normal gameplay.
 * While generating, all generation descriptions say "".
 * The time for generating this seed is also extraordinarily long. This might be because of the fact that the world is generated first (as normal) and then converted to the terrain thereafter.
 * The starting NPC is the Merchant instead of the Guide. He will sell the Furnace as per usual in the Jungle.
 * Larvae generate occasionally on the surface.
 * The Dungeon is painted orange and the Jungle Temple is painted green.
 * Water Chests and trees can generate in honey and Fallen Logs can generate on any surface tile.
 * When entering Hardmode, the two diagonal stripes of the new biomes generated will replace all Hive blocks to the respective Ebonstone, Crimstone, or Pearlstone Block and all Crispy Honey Blocks will be replaced by Hardened Ebonsand, Hardened Crimsand, or Hardened Pearlsand Blocks respectively. Note this only affect the initiate replacement and none of the biomes will spread to Hive or Crispy Honey Blocks.

Replaced tiles

 * All water is replaced with honey, unless on Floating Islands, in the Dungeon, or in the Cavern layer underneath the Ocean biomes.
 * All forest trees, Living Wood, Leaf Blocks and vines are converted into their respective Jungle variants, unless on Floating Islands.
 * Rarely, parts of the world that spawn above the minimum level needed for Floating Islands will also not be converted, leaving hilltops of dirt above a line.
 * All Sapphire, Ruby, Emerald, Topaz, Amethyst and Diamond blocks are replaced with Crispy Honey Blocks.
 * All Slush blocks are replaced with Honey Blocks.
 * All Dirt Blocks are initially replaced with Mud Blocks, unless part of Floating Islands.
 * Grass types above the lava layer of Caverns are replaced with Jungle grass, or Mushroom grass if below the lava layer. Corresponding grass is grown on all newly exposed Mud Blocks.
 * Because of this, a massive Mushroom Biome will appear in the lava layer of where the original Jungle was.
 * Stone, Granite, Marble, Ice and Snow Blocks above the lava layer are replaced with Hive blocks and Crispy Honey Blocks if below the lava layer.
 * Likewise with Ebonsand, Ebonsandstone, Hardened Ebonsand, Purple Ice, Crimsand, Crimsandstone, Hardened Crimsand and Red Ice blocks.
 * Only Sand Blocks within the Ocean biomes are replaced with Honey Blocks.
 * Likewise, only Hardened Sand and Sandstone Blocks within the Ocean biomes are replaced with Hive blocks.
 * Jungle grass and Mud Blocks that would be within 40ft of Ebonstone or Crimstone blocks are converted into Corrupt grass or Crimson grass and Dirt Blocks.
 * Newly added Mud Blocks underneath the Oceans, in the Cavern layer and above the lava layer, are replaced with Snow and Ice Blocks. The upper half will be Ice while the lower half will be Snow Blocks.
 * Copper Ore, Tin Ore, Iron Ore and Lead Ore in the approximate lower half of the world are replaced with Dirt Blocks.
 * Silt and Clay Blocks in the approximate lower half of the world are replaced with Stone Blocks.

Excluded content

 * The Oasis, glowing moss biomes, and Spider Caves will never be generated.
 * This also means the Stylist will never spawn.
 * The four types of micro-biomes (campsites, gemstone caves, moss chambers and Thin Ice patches) will not generate.
 * Lava traps and Geysers will not generate.
 * Shell Piles and Moss will not be added.

For the worthy



 * Seed (case-insensitive): for the worthy

This special world's features aim to drastically increase the difficulty of the game. It is referred to in the code as getGoodWorldGen. "For the worthy" directly references the tooltip of the Red Potion, "".


 * The world generation screen messages are spelled backwards.
 * All enemies' contact damage, health and coin drop rates are increased, in addition to the world difficulty multiplier, by their standard amount in a normal world. After that, the damage is increased by another . Damage from ranged attacks is typically left unchanged, with some exceptions including slow projectiles such as those from casters or Giant Fungi Bulbs.  For instance, in Expert mode, enemy health and damage are increased by 50% and 100% respectively compared to standard Expert mode; in Master mode, they are increased by 33.33% and 77.78% respectively compared to standard Master mode. To this point, many Hardmode enemies and bosses are capable of killing end-game characters in one hit.
 * It is impossible to achieve 100% Bestiary completion as there are no normal Bunnies and no Demons without voodoo dolls.
 * Bunnies (even placed) are replaced with Explosive Bunnies.
 * It is still possible to acquire normal Bunny item if the player catches a Bunny with a party hat (that spawns during the Party event), Bunny in a Santa costume (that spawns during Christmas) or a Bunny in a Slime costume (that spawns during Halloween) variant. Note that all of these variants have a separate Bestiary entry and do not count as regular Bunnies.
 * Blocks take only half as many hits with a pickaxe or drill to break, rounded up.
 * The Demolitionist replaces the Guide upon entering the world for the first time.
 * Some water pools throughout the world are replaced with lava.
 * Pots may drop lit bombs that shortly explode, instead of collectible Bomb items.
 * Trees often drop lit bombs when shaken, instead of their usual items.
 * Demonite or Crimtane and Gold or Platinum Ore generate more commonly as well as having larger vein sizes.
 * Spider Nests, Granite Caves, Marble Caves and Glowing Mushroom biomes are much more common.
 * Glowing Mushroom biomes are furthermore much larger.
 * Floating Islands are always infected with the world's evil biome, with matching Water Fountains.
 * Skyware Chests are replaced with locked Gold Chests but they still have their respective loot. However, it is still possible to get Skyware Chest loot before Skeletron via use of a Sky Crate.
 * The Dungeon is painted with seemingly random Deep Paint and filled with many more Spike traps. Additionally, the surface building of the Dungeon is inverted (the opening faces towards the nearest Ocean).
 * The Jungle Temple is painted with Deep Green Paint and is about three times as large as normal.
 * All chests have a chance to contain an Angel Statue instead of the first, usually most valuable item in the chest.
 * Red Potions can generate in chests. When consumed, these apply three random 30-minute buffs (instead of applying many debuffs like in other world seeds).
 * Glowing moss biomes are 50% larger.


 * It's possible for some random amount of Forest to be replaced with Jungle, still with all of the same structures that a Forest biome would have, like similar surface caves and a less open underground than a typical Jungle would have. It's even possible that the jungle will overwrite the spawn area and can take up nearly half of the world, from spawn to one ocean.
 * It's possible for the world to generate with no surface jungle at all.
 * The base value for coin drops from enemies is increased by 100%. This is in addition to the 250% increase already present in Expert Mode.

Underworld

 * The Ash Block ground of the Underworld is speckled with 1-block-sized pockets of lava. These won't hurt the player as of 1.4.
 * Digging up Ash Blocks will sometimes trigger other nearby Ash Blocks to fall (be affected by gravity), similar to Silt. This behavior is closely related to that of Cracked Dungeon Bricks.
 * All Ruined Houses are made of Hellstone Bricks.
 * All Demons are replaced with Voodoo Demons. It makes completing the Bestiary impossible in these worlds.

Bosses
Many bosses and/or their minions are either larger or smaller than normal:
 * Larger: King Slime, Eater of Worlds, Brain of Cthulhu and its Creepers, Queen Bee, Skeletron, The Hungry, Destroyer and its Probes, Skeletron Prime and Plantera.
 * Smaller: Wall of Flesh, The Twins and Golem.

As a general rule, bosses and their minions are affected by the same contact damage and health buffs reported above for regular enemies, while damage from other attacks is not affected. However, there are some exceptions. For instance:


 * The Eye of Cthulhu's melee damage in its second form is unchanged.
 * The Wall of Flesh has an additional 1.5x health multiplier applied after the regular for the worthy bonus, for a total of 25,200 maximum health in Expert mode and 28,560 in Master mode.
 * The Lunatic Cultist's damage from Ancient Light and Prophecy's End is increased, despite them being ranged attacks.
 * Duke Fishron's damage from Detonating Bubble, Sharknado and Cthulunado is increased, despite them being ranged attacks.
 * The Moon Lord's damage from any attack, including melee, is unchanged.

All bosses (with the exception of Duke Fishron and the Moon Lord, whose size is also not altered) receive certain changes to their AI:


 * Eye of Cthulhu
 * First form:
 * Spawns one more Servants of Cthulhu each cycle (4 -> 5).
 * When spawning Servants of Cthulhu, its maximum speed is faster (Expert: ->, Classic:  -> ); acceleration is also powered.
 * Then it will slowly charge to the player three times; the initial speed is increased (Expert: ->, Classic:  -> ).
 * The deceleration between two charges is enhanced and period of deceleration is shortened (Expert: 1.67s -> 1.42s, Classic: 2.5s -> 2.25s when 60 FPS)
 * Second form:
 * When heading to the player while above 50% health, the initial speed is increased by 20%.
 * When hanging in the air above the player, its maximum moving speed (which depends on distance to the player) is increased by ; acceleration is also powered.
 * Its melee damage is not changed in FTW world, i.e. even in this world, damage is still 36 in second phase and increased to 40 when below 4% health if difficulty is set to 2.00× Expert. (Possibly a bug?)


 * Eater of Worlds
 * All segments have +2 defense
 * Maximum speed is increased by (Expert:  ->, Classic:  -> ); acceleration is also powered.
 * Body segment can shoot Vile Spits under world surface in Expert Mode.


 * Brain of Cthulhu
 * Has +20% damage (applied before any Expert/Master difficulty bonuses)
 * Has +21 defense, making second phase battle extremely difficult when using most pre-Brain weapons (damage of those weapons are typically lower than 25).
 * Spawns with 40 Creepers, twice as many as normal.
 * When Creepers are charging at the player, their acceleration is about 8/3 times compared to Expert Mode. Creeper charging frequency is √(8/3)~1.6 times compared to Expert Mode.
 * BOC itself moves 3 times as fast in its first phase.
 * BOC has fully opaque shadow for the entirety of its second phase after taking its first damage, regardless of difficulty.


 * Queen Bee
 * Adds 0.5 enrage coefficient constantly, wherever the player fights with Queen Bee. The following discussion shows how enraged Queen Bee behaves differently.
 * Phase 0 (Dashing at the player)
 * Dashing is not strictly horizontal. With more enrage coefficient, the dashing can be more tilted.
 * Dashing speed increased (FTW contribution is ).
 * After dashing at the player, Queen Bee needs to adjust position. Enraged Queen Bee can adjust faster.
 * Braking capability after dashing is also enhanced.
 * Dashing distance is shortened (FTW contribution is 3.125 block tile width, or 6.25 longitude).
 * Phase 1 (Spawning Bees)
 * Spawns Bees more frequently.
 * Phase 3 (Shooting stingers)
 * Shoots stingers more frequently (FTW contribution is that interval of two stingers is 2 frames shorter (0.033 seconds if 60 FPS)).
 * Stinger speed is increased (FTW contribution is ).
 * Precision of stingers targeting the player is increased (FTW contribution is 24%).
 * In one phase cycle, Queen Bee will shoot less stingers (FTW contribution is 3).
 * If the Queen Bee cannot shoot stingers to the player due to its position, its acceleration to adjust itself is increased dramatically.
 * No changes applied to Phase 2 (Approaching the player to prepare shooting bees) and Phase 4 (Charging at the player if too distant).


 * Skeletron
 * When Skeletron is not spinning, its acceleration is increased. Comparing to Expert Mode, vertical acceleration is increased by 33%, horizontal acceleration is increased by 71%.
 * When Skeletron is shooting homing skulls at the player (in Expert/Master difficulty), frequency is increased by 25% (one hand down or life below 75%: 10 -> 13 per cycle, two hands down: 20 -> 25 per cycle).
 * When spinning at the player, its velocity is increased by 30%.


 * Wall of Flesh
 * Both mouth and eye have +3 defense.
 * Speed increased by 10% and then adds additional . Maximum speed increase to in Expert Mode.


 * Queen Slime
 * When performing her first phase slam attack, she does not pause between the rise and the fall and moves around much faster. She also launches 15 Gel per attack in her second phase, as opposed to 10. Also, the orientation of the Regal Gel attack is randomized.


 * The Twins
 * Retinazer
 * When shooting lasers in its first form, its maximum velocity and acceleration are increased by 15% (Expert: ->, Classic:  -> ).
 * Can shoot 5 more lasers at first form in one cycle (Expert: 9~21 -> 14~26 per cycle depending on health, Classic: 9 -> 14 per cycle, one cycle equals to 600 frames or 10 seconds if 60 FPS).
 * Initial velocity of dashing at the player in first form increased by, thus dashing distance increased (Expert: 13%, Classic: 17%).
 * Maximum velocity and acceleration in the whole second form is increased by 15% (Expert: ->, Classic:  -> ).
 * Spazmatism
 * When shooting cursed flames in both forms, its maximum velocity and acceleration are increased by 15% (first form: ->, second form Expert:  -> , second form Classic:  -> ).
 * Can shoot 4 more cursed flames in its first form in one cycle (Expert: 9~15 -> 13~19 per cycle depending on health, Classic: 9 -> 13 per cycle, one cycle equals to 600 frames or 10 seconds if 60 FPS).
 * Initial velocity dashing to the player in it's first form is increased by 20%, thus the dashing distance is also increased by 20%. Second form is not affected.


 * Skeletron Prime
 * Bombs shot by the Prime Cannon destroy blocks.


 * The Destroyer
 * Has twice as many segments (80 -> 160).
 * Acceleration increased.


 * Plantera
 * Maximum speed and acceleration increased by 15% (Expert: 20/34/45 mph -> 23/39/52 mph, Classic: 13/26/36 mph -> 15/29/41 mph at 100%/50%/25% health).
 * Projectile frequency increased (one more projectile in time interval: Seed 1.33s, Poison Seed: 1.83s, Thorn Ball: 3.33s if 60 FPS).
 * More Plantera's Tentacle in second form (around Plantera: +6, around Plantera's Hook: +3).
 * Plantera's Tentacle's speed dramatically increased (however this speed increase actually makes Tentacles fixed at a position around Plantera or her Hook at a radius depending on health value, instead of swinging which actually makes the battle more complicated).


 * Golem
 * Attacks significantly faster, in addition to being able to phase through blocks much faster. In the second stage, the body jumps much higher and the head fires lasers faster.


 * Empress of Light
 * Cycles faster between attacks (0.75s/0.33s -> 0.38s/0.17s for normal/enraged stage).


 * Lunatic Cultist
 * Cycles faster between attacks.

Celebrationmk10



 * Seeds (case-insensitive):

This seed celebrates Terraria's tenth birthday, May 16, 2021.

Overall

 * The spawn point can be on the left or right edge of the world, implying most of the spawns usually happening in the inner third of the world will happen in the left or right sixth of the world.
 * Andrew the Guide, Whitney the Steampunker, Yorai the Princess, a Party Girl, and an Angora Town Bunny will also spawn there and a Party immediately starts.
 * A majority of the world is painted: The Dungeon is in deep pink, Living Trees, the Pyramid, and Clouds on Floating Island are painted in pink, the Jungle Temple is painted with purple tiles and cyan walls, and all Sand Blocks, grass, and surface objects are painted in cyan.
 * There are even more Living Trees than in a drunk world.
 * Items in Chests always have a "best" modifier.
 * Accessories will have one of the +4 modifiers (Lucky, Menacing, Quick, Warding).
 * Weapons will have modifiers with the most stat increases, according to their damage type. The possible modifiers are:
 * Legendary, Godly, or Ruthless for melee weapons
 * Unreal, Demonic, or Ruthless for ranged weapons
 * Mythical, Demonic, or Ruthless for magic and summon weapons
 * Note that this generation is beyond the "modifier limit". For example, it is possible to get a flail with the Legendary modifier, which is impossible in a normal world.
 * Half of the Underground Cabins have their tiles and walls replaced with Rainbow Bricks, and a half of the remaining ones are painted with a diagonal rainbow pattern.
 * Gem Trees are more common, similarly to the drunk world.
 * All Floating Islands have Hallowed grass and a Hallowed Water Fountain.

Desert

 * The Desert generates without its usual entrance but with a single Pyramid.
 * The Chest in the Pyramid always contains a Pharaoh's set in addition to its normal loot.
 * The caves of the Underground Desert are smaller.

Other changes

 * Two unique enemies can be encountered in this seed:
 * The Jungle Mimic can be found in the Hardmode Jungle.
 * Golden Slimes can rarely spawn.
 * Fairies are less rare and most of them are Pink Fairies.
 * Uncommon and rare enemies seem to have a higher spawn rate.
 * Hearts and Stars can always spawn as their seasonal variants.

 * Fireflies and Butterflies are more common.
 * The chance of obtaining a developer set from a Treasure Bag is doubled, and developer sets can be obtained from any Treasure Bag.
 * The chance for nights with an increased Fallen Star rate is doubled.
 * More clouds spawn in the background and more of them have a special shape.
 * The Steampunker and the Princess can always spawn.
 * Every non-corrupt tree grows as a vanity tree.
 * Most bosses (including the Celestial Pillars and the bosses' minions, but except the Leeches, Servants of Cthulhu, King Slime, Queen Slime, Plantera, Golem, Betsy, Lunatic Cultist, and the Moon Lord) are smaller than normal.
 * The Traveling Merchant always sells 2 more items than normal.
 * The Princess sells rare items:
 * Slime Staff

 * Flask of Party
 * Sandstorm in a Bottle (while in the Desert)
 * Terragrim (during a Blood Moon)
 * Pirate Staff (after beating a Pirate Invasion in Hardmode, during the following moon phases: )
 * Discount Card (after beating a Pirate Invasion in Hardmode, during the following moon phases: )
 * Lucky Coin (after beating a Pirate Invasion in Hardmode, during the following moon phases: )
 * Coin Gun (after beating a Pirate Invasion in Hardmode, during the following moon phases: )
 * The Wizard Hat grants an additional minion slot.

Trivia

 * The discovery of the drunk world originated from an image posted in a tweet by Redigit, featuring the release date and the new world generation screen.
 * Using the Demon Conch in a new drunk world will not transport the player to the Underworld but will do nothing, as it requires solid ground to place the player on.
 * The smiley-faced moon seen during the generation of a drunk world is a reference to an astronomy hoax.


 * "Not the Bees!" is also an achievement for firing a Bee Gun with a full set of Bee armor equipped.


 * Because of how stat scaling is implemented, the health and damage is doubled instead of simply adding one to the multiplier in For the Worthy seeds.
 * This results in Journey Mode Expert difficulty enemy health being equivalent to non-Journey Mode Master difficulty enemy health. Outside Journey Mode, Master difficulty enemy health in "For the worthy" is ×4 base health whereas in Journey Mode it is ×6.
 * Damage dealt by enemies also scales higher in Journey Mode. Just like Journey Mode Expert difficulty health is equivalent to non-Journey Mode Master difficulty, enemy damage appears to scale in a similar manner.
 * In "For the worthy", several mechanics reference very early versions of Terraria where they were standard behavior: This includes the Locked Gold Chests generating on Floating Islands, Ash Blocks collapsing at random and Chests containing an Angel Statue instead of a valuable item.


 * The names of three of the starting NPCs in the Celebrationmk10 seed are the names of three members of Re-Logic: Redigit (Andrew), Cenx (Whitney), and Yoraiz0r (Yorai).


 * Due to the way Drunk and Celebrationmk10 seeds are implemented, the list isn't exhaustive and any number of 0 can be added before the number seed. Also many other unintended seeds have the same result, like (case sensitive) :
 * "now aunt brush", "Joke Disappear Horizon" and "disapprove stiff solution" produce a drunk world.
 * "Thirst of dress", "engineer governor reproduction" and "inform Representative yorai" produce a celebration world.
