Goodie Bag

The Goodie Bag is a grab bag-type item available during the Halloween seasonal event (October 20 - November 10). Each contains one random reward from the list below. Goodie Bags are opened by right-clicking them from within the player's inventory, similar to Presents, Crates, Herb Bags, and Golden Lock Boxes. They are dropped by any enemy except statue-spawned enemies and Meteor Heads, with a 1/80 (1.25%) chance, during Halloween only.

Most Goodie Bag rewards are vanity items and decorative furniture, with the exception of the Bat Hook, Rotten Eggs, and Unlucky Yarn. The most common rewards are Rotten Eggs.

All pieces of the vanity sets will be received together with the exception of Cat Ears.

Goodie Bags will not drop from enemies spawned from statues. If they did, then they would be far too easy to obtain, and therefore defeat the challenge of receiving the more rare items wielded from the bags.

Trivia

 * Many of the vanity sets are references to popular culture. The Creeper set is in reference to the sandbox game Minecraft, the Space Creature set is in reference to the Xenomorph creatures from the film Alien, the Karate Tortoise is a play on words in reference to Teenage Mutant Ninja Turtles, the Leprechaun set is a reference to reports of a leprechaun sighting in Mobile, Alabama, | Reddit post by Redigit, | Remix of the report that Redigit looped while coding, and the Bride of Frankenstein is referencing the film The Bride of Frankenstein.
 * The "Jacking Skeletron" painting is a reference to The Nightmare Before Christmas, in which the main character is Jack Skellington. The scene depicted in the painting is of Skeletron at an iconic location from the movie.
 * Due to the high sell rate of the items and the bags themselves, end-Hardmode players can farm the Dungeon and reap many Platinum Coins from the Dungeon Spirits and dungeon drops.
