Bunny

The Bunny is a benign background character that cannot harm players. Bunnies have only 5 health, and can be damaged by other mobs, which always results in their instant death.

Bunnies will mainly spawn in the middle third of the above-ground world, and only on ordinary Grass. They can also spawn in outer parts, but only if a house is present.

During a Blood Moon, or when hit with Vile Powder, Bunnies will turn into Corrupt Bunnies, which have much more health and are aggressive.

If you have a Wizard in your world, the bunnies will be attracted to the dwelling of the Wizard.

Trivia

 * The Bunny can be seen on many of Terraria's logos.
