Super Mario Galaxy - Bubble Blastoff

Deep Dark Galaxy - Mission 2
Bubble Blastoff

I dawdled around here. I admit to that. Also, I chose this mission because of the sheer randomness. I mean...you hit a watermelon with tennis balls to make it expand, then when it covers the planet, it gives you a Star.

Also, I missed the Invincibility Star a second time in a row. Ugh.

A distinction this mission has is that it features the only Cheep Cheeps in the game. Ain't that awesome?
