Tap
Strike, Slap
On your mouth is a stamp that you tap, strike and slap to create a beat! The stamp looks like a little drum, but you're really just hitting your mouth for fun (the stamp was an excuse to make it seem normal).

When you tap and strike the stamp on your mouth, you make a ta-ta (たた) sound. Imagine yourself making a beat with the little stamp drum on your mouth. Now listen... たた! There! Did you hear it?
