Secret world seeds

Some world seeds have been discovered as secret easter eggs, and generate worlds with strange or unique features. Some can drastically affect world structures and biomes, game mechanics, and/or theme music.

Worlds created with these seeds will not be identical, despite having the same seed. Usage of a secret seed overrides its use as a source of randomness.

Drunk World


This seed references the date of 1.4's official release, 5/16/2020, and generates a strange world referred to in the source code as.
 * Seeds:  or


 * Both World evils generate, each on opposite sides of the world, and both the Corruption and Crimson Biome Chests are present in the Dungeon.
 * On a Blood Moon or Solar Eclipse, the Dryad and Steampunker will randomly either sell the Corruption or the Crimson corresponding items, not both.
 * When turning a world to Hardmode, only one evil is picked to be opposed to the Hallow.
 * The world icon in the world selection menu shows a tree infected with both world evils.
 * Both ore variants for each tier are generated in the world.
 * This applies to Hardmode ores as well, but requires breaking six Demon or Crimson Altars for all ores instead of three. Breaking the first three Altars will spread Hardmode ores like normal and breaking the next three Altars will spread the other variant. Breaking more Altars will repeat the cycle, generating more veins of these ores.
 * 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.
 * Living Trees generate much more frequently on the surface, many of which are clustered and interconnected underground.
 * Moon Lord Legs and Red Potion items can generate in Chests.
 * Marble and Granite caves swap their structures.
 * Jungle and Snow biomes generate on the same side opposite of the Dungeon.
 * The Dungeon generates underneath a "dead" Living Tree. The tree will be painted brown, and the Dungeon painted red, yellow, blue, purple, or brown.
 * The surface entrance is completely removed, and the Old Man is placed in a pre-generated house underground, making it harder to defeat Skeletron.
 * The Dungeon contains Chippy's Couch.
 * The Jungle Temple is painted green and is much larger in size.
 * Bee Hives are replaced with oversized variants, hosting multiple Larvas.
 * The Underworld layout is inverted, with the middle third as a continuous lava lake and the two thirds at the edges containing Ruined Houses.
 * 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.
 * Both Oceans have a much higher chance to generate as the ocean trench variant.
 * While generating:
 * The background shows a Glowing Mushroom biome and rapidly scrolls towards the left.
 * The moon moves backwards through the sky and resembles a glowing smiley face, referencing a popular astronomy hoax. The clouds resemble Redigit's head.
 * The generation descriptions and tips become random numbers that change every tick (except when "placing traps").
 * The outline of the progress bar rapidly flashes between Corrupt and Crimson.
 * The Title (Console) theme will play instead of the normal title theme.

Not the bees
This seed references a meme from the 2006 remake of the film The Wicker Man. It generates a world dominated by bee-themed biomes and bee-related items and structures.
 * Seed:  or   (case insensitive)


 * While generating, the generation descriptions all say "Generating Bees".
 * Forest is replaced with Jungle.
 * Hive Blocks replace Stone Blocks.
 * Honey Blocks replace Sand Blocks in the Ocean.
 * Hornets and Larva can appear everywhere.
 * The Dungeon is Painted orange.
 * The starting NPC is the Merchant instead of the Guide.
 * The Merchant will also add a Furnace to his wares, as it would be impossible to craft one otherwise.
 * Queen Bee spawns at the edge of the world.
 * All Water is replaced with Honey except on Floating Islands.
 * The Desert and evil biomes are not affected.
 * The border between the Caverns and Underworld layers are always Glowing Mushroom biome.
 * Most of the Mud Blocks in the Glowing Mushroom biome are replaced by Crispy Honey Blocks.
 * The snow biome is composed solely of Hive blocks.

For the worthy

 * Seed:  (case insensitive)

This special world's features aim to drastically increase the difficulty of the game. It is referred to in the code as.
 * The world generation screen messages have backwards text.
 * The Demolitionist replaces the Guide upon entering the world for the first time.
 * Some water pools throughout the world are replaced with lava.
 * Pots drop lit bombs that shortly explode, instead of collectible Bomb items.
 * Trees drop lit bombs when hit, instead of their usual items.
 * Enemies have increased health and massively increased damage. (eg. Demon Eyes pre-Hardmode deal 40 damage to a character in full Solar Flare armor).
 * Bosses have doubled health, on top of previous Expert/Master bonuses.
 * Many bosses are either larger or smaller than normal:
 * Larger: Skeletron, King Slime, Destroyer, The Hungry, Plantera.
 * Smaller: Golem, Wall of Flesh, The Twins.
 * Spider Nests, Granite Caves, Marble Caves, and Glowing Mushroom biomes are much more common.
 * Glowing Mushroom biomes are much larger.
 * Floating Islands are always infected with the world's evil, with matching water fountains.
 * Skyware Chests are replaced with locked Gold Chests.
 * The Dungeon is painted with vibrant colors 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 green and is much larger.
 * Underworld:
 * The Ash Block ground is speckled with 1 block-sized pockets of lava.
 * 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.
 * Wood Chest/Water Chest loot can contain a single Dirt Block along with their standard loot.
 * Red Potions can generate in chests. When consumed, these apply 3 random 30-minute buffs (instead of applying all debuffs like in other world seeds).
 * Bunnies are replaced with Explosive Bunnies.
 * Skeletron Prime's bombs destroy blocks.
 * The Lunatic Cultist cycles faster between attacks.
 * All Blocks take only half as many hits with a pickaxe to break, rounded up.

Trivia

 * The discovery of Drunk World originated from an image posted in a tweet by Redigit, featuring the release date and the new world generation screen.
 * The moon forming a smiley face in the world generation screen of Drunk World is a reference to a meme stating that "The moon, Jupiter and Venus will form a smiley face on May 16th, 2020", the date 1.4 was released.
 * The Moon Lord Legs is likely Redigit's answer to a petition to add the Moon Lord's legs to the 1.4 version of the game.
 * Not the Bees! is also an in-game achievement for firing a Bee Gun while equipped in a full set of Bee Armor, which in itself is a reference to in the 2006 mystery horror film .
 * For the Worthy is a reference to the tooltip for the Red Potion and is the only world where the potion gives buffs rather than debuffs.
 * All of the seeds change the loading screen when changing the world, and also change the guide to another NPC.
 * The generation of locked gold chests on Floating Islands in the "for the worthy" seed is a reference to earlier versions of Terraria, where Floating Islands contained locked chests. This usually caused them to be inaccessible until defeating Skeletron.
