Snail

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 634.3 Hz, 67 cents flat of E5, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap to make it hide in its shell. Hands-on: poke it and it hides; lift it by the shell.

A snail carries its home on its back: a coiled shell it can pull its whole body into. It glides along on one long, muscular foot over a thin layer of slime, and its eyes sit at the tips of its two long upper tentacles. In dry weather, a snail can seal its shell with a layer of dried slime and wait for rain.

Tap it and it hides, as a real snail does: the eye stalks roll in first, then the head and the foot are drawn in through the shell's opening, and the shell settles on the ground. Tap again and it slides back out, the eye stalks unrolling last. With ✋ Hands-on on, poke it and it pulls in quickly; pick it up by the shell and drop it, and once it is back on its foot it slowly comes out again.
