On to business: That jumpy little bugger is the Piledriver Micro-Goomba. He hangs out with real bricks pretending he’s one of them. Trick is, he doesn’t shine like them. That let’s you pick him off early. Otherwise just jump on the brick when it lands. It seems easy but when there’s like 5 of these guys jumping it’s easy to take at least one hit before you get away.
