World 1: Ice World
Work your way to this area. Make sure you do not permanently kill the blue fuzzes (with Rumia Yoshi, Yin Yang balls, or a drill). Bounce off this blue fuzz to get on top of the level.
Head all the way to the right past Chibi Koakuma and you'll reach Adult Koakuma at the end. Don't drop straight down, or you'll fall in the pit.
Grab the broom from the save point, and make sure you still have it when you reach Chibi Koakuma.
Jump off the cloud to the right and hover over to the next platform.
Kill the fuzz and use the platform to takeoff. Fly between the set of spikes to land on the other side, and jump over to the right to find Koakuma.
