Bizarro-Rabbit
Bizarro-Rabbits are white imperfect rabbits on the planet Htrae who resemble other Bizarro creatures on the Bizarro World. When Easter arrives on the Bizarro world, Bizarro-Rabbits search for square eggs that bizarro children hide, unlike Earth where the Easter Bunny hides Easter eggs and children go searching for them (Adv No. 295/2, Apr 1962: "The Kookie-Super-Ape!").
