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 and Crates. 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.
