Super Mario Galaxy 2 "Final Boss Battle"

Super Mario Galaxy 2 "Final Boss Battle" is a gameplay video uploaded on the main channel in June 2010. The video notably broke the record for the longest video on the channel, which was previously held by The Nintendo DSi. The video features Logan playing through Bowser's Galaxy Generator, the sixth Grand Star level in Super Mario Galaxy 2, which was released just a week prior to the video being uploaded.
