Bunnymund, you are...
Bravely there fro any one, child, in need of a guardian, and/or lost/needs hope.
Uniquely talented in Tai Chi, Martial Arts, using boomerangs, and delivering thousands upon thousands of eggs in one day.
Nemesis with Jack, cause of Frosty's nickname he gave Bunny: Kangaroo.
Never caught without an egg and paint brush.
You will never be alone if your down, for he will always be there in your presence even when you don't sense it.
Miniature when he's not believed in.
Unnaturally tall and muscular.
Never slow, so don't race him.
Don't threaten the children of the world, fro there will be flying exploding eggs in your future.
