You’ll see many enemies you can copy off from then icicles falling. Enter the door far right and battle Mr. Frosty. This mini-boss will throw ice blocks so spit them back. Defeat this mini-boss and Kine will be free. Swim through the water as you’ll find many weeds and frogs. Swallow the blocks then use the door ahead. Watch for thief copters and other enemies as you cross an area full of thin ice and you’ll find the goal ahead.
