Wrecking Crew (WarioWare: Twisted! microgame)
From the Super Mario Wiki
The objective is to have Mario get all the Eggplant Men away from him by hitting bombs with his hammer, thereby destroying the ladders. The view begins at the side (like the original game), but quickly changes to a top-down one. If Mario gets hit by an Eggplant Man, he will fall off-screen and the player will lose the microgame.
Very rarely, it is possible to win by standing still.
