World 3: Hills/Volcano World
Collect the broom before the savepoint. You must keep this until the end, so don't lose it. If you get Rumia Yoshi, you will still have your broom after it wears off.
When you get to the platform with 3 screws, kill the enemies and drill the screws into the ground. Use this space to takeoff and hover until you land on the high brick platform.
Jump over to the stone platform and Koakuma.
Work your way to the end of the level. Instead of going to Chibi Koakuma, jump on top of the tall screw (serving as a flagpole from the original Mario games) and drill it deep into the ground to find Adult Koakuma.
