Archived Kimimaru4000 video from YouTube. Original description mostly intact:

This is a speedrun of battling Bouldergeist in Super Mario Galaxy. Enjoy!

Parts of improvement: After Bouldergeist only has his head left at the beginning, I could've done a spin-long jump to hit him faster. Near the end, I missed a bomb-boo.

Play Time against Bouldergeist: 0:54
