FitPals
A shake-the-tray settling toy for ages 3–5: jostle the loose shapes and watch each one click home in the hole that fits. You cannot steer them — they tumble until they fit. Calm, no-fail, on-device.

Meet the cast
FitPals's little friends gather round the shaking tray. Jibble shakes it and watches the shapes find their places — you cannot aim them, they only tumble until they fit. The shapes themselves have no faces; the friends are the ones watching and cheering.
Jibble
(Guide) shakes the tray and watches — the shapes settle by tumbling, never by aiming (settles-not-steered)
Plink
Loves the soft click when a shape drops into the hole that matches it (only what fits can rest there)
Twiggy
Shakes and shakes — some tumbles miss, some fit; patience while the shapes find their places (random jostling)
Fernly
Loves the calm, finished tray when every shape has found its place (the settled resting state)
