KneeTots
A knee-bouncing rhyme for a grown-up and a little one. Each bounce sings the next line at your own pace; tip back to land the last line. Then the screen rests and the rhyme is yours. Ages 3–5.
▶ Play it nowBuilt for sittings of about 10 minutes on the screen. That is our design budget, not a measurement.

Meet the cast
KneeTots has two friends who love a lap game. Boingle bounces only when you bounce, and Tiptuck waits for the tip at the end.
Boingle
bounces only when your knees bounce, so the rhyme keeps your beat, not its own
Tiptuck
A round tortoise - tips back slowly at the end of every rhyme, because the last line lands only on the tip
