Halloween

During Halloween season, which lasts in Terraria from October 20 until November 10, several enemies wear costumes that change their appearance (though not their abilities) such as slime bunnies, bunny slimes, and superhero zombies. Ravens and Hoppin' Jacks will appear during the night while Ghosts will occasionally appear Underground (the two latter only in Hardmode). A number of town NPCs sell additional items. Stars have their appearance changed to Soul Cakes, and Hearts have their appearance changed to Candy Apples. Goodie Bags can also drop from any mob with a 1/80 or 1.25% chance, which allow the player to collect numerous Vanity Items, Paintings, and a Black Cat pet. Pumpkins also grow naturally like flowers, and all enemies besides statue-spawned enemies or Meteor Heads have a 1/2000 or 0.05% chance to drop a Bloody Machete or Bladed Glove.
