- Not to be confused with the Treasure Bag, a similar, Expert mode-exclusive item.
The Goodie Bag is a grab bag-type item available during the Halloween seasonal event (October 20th - November 1st). 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, Treasure Bags, 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 costumes (56%) or Rotten Eggs (25%), with occasional paintings (7%). Rarely, the bags can include a Bat Hook or Unlucky Yarn. Costumes are mostly two or three pieces received together, and sell for 60 per piece. However, Cat Ears do come alone (and are not connected with the three-piece Cat costume). The paintings sell for 10 each.
- A good way to quickly acquire a large sum of Goodie Bags is to spawn a Goblin Invasion or other event.
