Super Mario Galaxy 2 #8 - Bowser Jr.'s Fiery Flotilla
Super Mario Galaxy 2 Runthrough #8
Star: Gobblegut's Aching Belly
Bowser Jr. seems to act independently from Bowser. He gets a medium sized fortress with a handful of enemies, which is just good enough for a light assault on Mario.
Then you see the little tyke call forth a giant... wormy snake. I'm not sure what Gobblegut would count as, but it could be an eel with a snake... don't ask me!
I have not tried, but it might be possible to bust four of those spots before he goes into "rage mode". There is six of them, and they get harder to hit when he's angry. That's why I waited for the first three to pass-by, so I can save them for the later phase.
