Snow B

Snow B is the first guardian level in the Game Boy Color adaption of Croc.

Walkthrough
Destroy the Smash Boxes and grab some crystals, then move past the Beaver and exit at the top of the hut.

Itsy will leap over Croc, and when he does, he'll be briefly confused. Hit him and he'll shatter into two smaller versions of himself, that can be defeat in the same way.

Trivia

 * This is the equivalent to "Itsy the Ice Demon".
