Halloween

The Halloween Event is a special event in Terraria, which lasts from October 25 until November 10. During the event, several NPCs wear costumes that change their appearance (though not their abilities) such as slime bunnies, bunny slimes, and superhero zombies. 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.
