Step 1: walk towards a gap. the screen will rumble and he will roar. frostwind will say "Weak little hero... your time is at end. feel my wrath!" then shoot him.
step 2: after he falls, run to the edge of the screen. when he gets close to you, shoot him. he will dive down into the gap. Get snowballs by ground pounding the snowy lump. Repeat until you get to the next stage.
Stage 3: you will jump auto matically and land on a snowy island. you will see heathe locked up, out of reach. frostwind will attack the cage. when he flies, stay in the middle. he come in the gap. he also will shoot ice after he come up. when he comes up a second time, shoot him with your snow shooter. when he's unconcient, ground pound his head. repeat until he is defeated.
