This is part 32 of a 100% walkthrough for Super Mario Galaxy. This video includes the Final Bowser Boss fight in Bowser's Galaxy Reactor. The game requires you to beat Bowser again after getting 120 stars for an alternate ending. You also unlock Luigi as a playable character. I still have more stars to collect after defeating the final boss so this is not the finale. Super Mario Galaxy 100% walkthrough playlist:.
