Vicious Bunny

The Vicious Bunny or Crimtane Bunny  is an enemy that results from a Bunny that has been corrupted, either by the player using Vicious Powder or by a Blood Moon event on a Crimson world.

Trivia

 * On the world creation menu, the Vicious Bunny is used as the icon for Master Mode.
 * Despite its name being the Vicious Bunny, the kite based on and dropped by it is called the Crimson Bunny Kite. The Corrupt Bunny Kite, on the other hand, is correctly-named.
