It's not everyday you meet a giant rabbit who can do magic...

Nanabozo, the Great Rabbit, is... well, a giant rabbit. He's also a powerful sorcerer, and Rainbow's spirit guide, as Great Eagle is for Yakari. When he appears to the young Sioux to tell him his charge has disappeared, little Yakari is swept up in a quest that will make him turn into a giant, run on smoke, fly, and travel to the ice banks where the polar bears play.
