Alien Bunnies, originally known as Space Hares, are a recurring alien species in the WarioWare series. They originally appear as the life counter for Orbulon's games in WarioWare, Inc.: Mega Microgame$! Every time the player loses one of their lives, an Alien Bunny gets sucked into a nameless void. Regaining a life brings one back from said void. Their spaceship appears in the Dribble and Spitz microgame, Space Escape.
In WarioWare: Twisted!, Alien Bunnies show up during Orbulon's story as his minions.
