Slippery Hockey is a minigame in Densetsu no Stafy.
How to play
Use the control pad to move Moe left or right. Press and hold the B button while moving to move faster. Press the A button to shoot Starfy. After you shoot Starfy you can press the A button again when he's near you to give him a speed boost. Your goal is to beat your opponent at hockey with Starfy serving as the disk. The first player to reach 3 points is the winner. If time runs out the one with more points will win.
