Hey did you know Pit could side-b Pacman's trampoline? Here's what it looks like
If you time it right you can side B, push it, jump on it while in side-b's lag without moving, act again.
Or even simply push it away from pacman while he's trying to recover.
And if you want to be really fancy you can try to push the red trampoline into pacman, but good luck landing that one since it always goes the same angle.
