Bunny

The Bunny is a background character that cannot harm players. Bunnies have only 5 health, and can be damaged by other mobs including the player, which almost 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 areas nearby a house, including the Underworld.

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

Trivia

 * The Bunny can be seen on many of Terraria's logos.
 * If stone is corrupted or hallowed in the Underworld after the Wall of Flesh is defeated, bunnies can spawn there.
