Nintendo's confirmed that Super Mario Galaxy 2 will come with a bonus DVD, which is meant to help players master the mini-plumbers skill set.
In a masterstroke of impracticality, however, the disc won't work on the Wii itself. How's that for a massive slice of inconvenient cake?
If you do happen to have something else that the disc will play on though, you'll gain valuable information about the plumber's planet jumpy approach to life, how to use the Wii Remote and nunchuck together, starbits, navigating between worlds and everything else you need to be a master of the galaxy.
We brought you the news that Super Mario Galaxy 2 will feature a two player mode back in April.
