Rhythm Rally 2 (かえってきた ピンポン?, Kaettekita Pin Pon), known in Rhythm Heaven as Rhythm Rally (ピンポン?, Ping-Pong), not to be confused with it's sequel in Rhythm Heaven, is the 6th minigame in Rhythm Heaven and the 54th minigame in Rhythm Heaven Megamix. It features two Paddlers playing a table tennis rally game together. In Rhythm Heaven Megamix, instead of a featureless white plain, the background is a big strawberry cake and it acts as a sequel to Rhythm Rally.
The game starts after a whistle. You are a Paddler who is playing a table tennis match with their rival. Your rival will serve a ball to you, & you need to hit it back. There are three speeds of served balls: The normal ball, which goes normally as it bounces smoothly; the slow one, goes a little slower as it bounces higher; and the fast one. Before each fast one, there is a cowbell sound before it to warn you that it's coming at you in fast speed, so hit it as soon as possible. Each cue goes at the same basic speed, but there are different intervals and mixes of them.
