Cold Cuts level 2-4 is the introduction of the Ice bird! Send him straight ahead, into the bottom part of the structure. On contact, he freezes everything he touches. Also, after 2 seconds, or upon manually triggering, a cold blast freezes everything in a small radius. So, when you send him straight ahead, trigger his ability upon contact. Then take out the structure with the Blue birds.
Debut: This level is the debut of the Ice Bird. He freezes everything within a large radius of where it touches.
