The fifth world in the game Banjo-Kazooie for the Nintendo 64 and Xbox Live Arcade. Its a level with a gaint snowman. It has annoying snowman enemies called Sir Slush, they throw snowballs at you. You can find a giant Christmas Tree and a Walrus named Wozza. It's also the world where you meet Boggy the polar bear for the first time. It's my favorite level. :)

Literally everyone, ever. Including the writer of this definition.
