Super Mario Galaxy 100% Walkthrough - Part 26 - Bowser's Galaxy Reactor (Final Boss Fight + Ending)

This is part 26 of a 100% walkthrough for Super Mario Galaxy. This video includes the Final Bowser Boss fight in Bowser's Galaxy Reactor. This video also shows the ending and credits for the game. I still have more stars to collect after defeating the final boss so this is not the finale.
