Bombs Away (microgame)
From the Super Mario Wiki
Wario is standing on the side of a mat, and the player (represented by a boy) on the opposite side. There are two countdown bombs on each side. The player can touch the bombs to push them to Wario's direction, as Wario can push them toward the player, too. The objective is to pass one of the bombs to Wario when it's reaching zero, causing it to explode on him. However, the countdown is restored each time the bomb is pushed. The player wins if Wario is blown up by a bomb, but loses if Wario hits them.
