Creeper set

The Creeper costume is a set of vanity items made up of the Creeper Mask, the Creeper Shirt and the Creeper Pants. These items are all supposed to be equipped in the Social slots as they only provide a visual appearance.

It has a chance to be obtained by opening a Goodie Bag from the Halloween Event.

Trivia

 * Re-Logic was given permission by Markus Persson (aka Notch, the creator of Minecraft) to add the Creeper Costume to Terraria.
 * Unlike other costumes, the creeper costume has three visible legs which have their own walking animation.
