if you're playing on an actual DS, the ping pong minigame in WarioWare Touched is silly and fun for a bit. Gotta unlock it first though and it's the only multiplayer part of that game iirc.
it's cute because both players play using the same DS, it's just a timing game where you each hold it, one player uses L and one uses R to hit the ball. Surprisingly good fun :D
