so the giant mutated rabbit was a giant mutated rabbit in his previous life!!!!! XD.. & the same goes for sandman!!!....i like the fact that they are from different cultures like you got russian, australian, american, indian/indonesian & i don't know about sandman!!
Bunnymund is a Pooka a kind of fairy that takes on the appearance of a giant rabbit.
And you DO NOT I repeat YOU DO NOT want to get on a Pooka's bad side they will beat you up and spit you back out before you can say "oops". Some of the fight scenes we saw Bunny in should be proof enough.
Bunny is according to the books the last of his kind so Pitch must have destroyed his homeworld, it's hinted in the books that Pitch has destroyed entire planets.
Uhm, I took the background according to the books. The giant mutated rabbit is not even from earth, same goes for Sandy. XD Bunnymund create Australia, so the animation team came up with the idea of making him Aussi, it's totally fine. As for Sandy, he's not bound to one specific culture. Yes, I love the cultural relation of the others too.
ok....but don't you think it would be cool if sandy was desended from somewhere in the middle east, were there is alot of sand!!!!....i took a look on the original books & sandman world kinda has the artchitecture similar to that of princess jasmine in Agrabah in disney aladdin!!!,.... then again it would be cool if sandy has some arabian traits to that of Shahrazad, whom likes to tell stories of arabian night tales before sleep!!
