Goodie Bag

The Goodie Bag is a grab bag-type item available during the Halloween seasonal event (October 20th / October 1st  until November 1st  / November 10th ). Each contains one random reward from the list below. Goodie Bags are opened by pressing from within the player's inventory, similar to all other grab bags. They are dropped by any enemy except statue-spawned enemies and Meteor Heads, with a 1/80 (1.25%) chance, during Halloween or a Pumpkin Moon only. Additionally, if wave 15 is reached in the Pumpkin Moon event, the enemies listed above can also drop Goodie Bags for the following day until 4:30 am.

Most Goodie Bag rewards are vanity item sets (56%) or Rotten Eggs (25%), with occasional paintings (7%). Costumes are mostly two or three pieces received together, and sell for per piece. However, Cat Ears do come alone (and are not connected with the three-piece Cat set). The paintings sell for each.

Tips

 * Goodie Bags can quickly be acquired by buying a load from the shop. Or I have found really good deals on Amazon. The problem with that though is that delivery costs an arm and a leg and another leg, and perhaps a hand or two. While Water Candles and Battle Potions increase the regular spawn rate, events like the Goblin Invasion or the Slime Rain prove to be even more effective.

Trivia

 * Many of the vanity sets are references to popular culture:
 * The Creeper set is a reference to the sandbox video game .
