Desert B

Desert B is the third guardian level in the Game Boy Color adaption of Croc.

Walkthrough
Grab the crystals and swim through to the boss arena.

Cactus Jack will spin around, spinning out needles at Croc. Duck to avoid them and then, when he's dazed, tail-whip him. If you get hit at any point before he's dazed, he won't enter this stage.

Three hits and you'll have defeated him.

Trivia

 * This is the equivalent to "Cactus Jack's Ranch".
