Madcap's latest creation, the Ice Crusher, puts the whole city in a deep freeze, forcing Axel and the team to face him in a game of high-stakes hockey or risk slip-sliding into another ice age!.

Axel discovers that the culprit behind Bobbie Blobby's missing mech-suit is Masko, who only wanted to clean out its clogged clay cannons, but lets the suit fall into the hands (or tentacles) of Dr. Nautilus - intent on flooding the sewers!.
