A squeezed rubber toy: a quick rising squeak with a wobble in the middle, then a smaller second squeak as it springs back. Use it for cartoon reactions, clumsy characters, footsteps on a toy, or a door that is embarrassed to be opened. Round, plastic, and slightly out of breath.
squeak 1: triangle sweeping 620 Hz -> 1180 Hz over 120 ms, then back down to 780 Hz in the last 60 ms wobble: pitch multiplied by 1 + 0.06 sin(2 pi 18 t), so it warbles as it is squeezed squeak 2: same shape at 55% level, 780 Hz -> 1040 Hz, starting at 170 ms envelope: 4 ms attack, held flat to 130 ms, then a 50 ms linear release (a squeeze, not a click); the second squeak holds to 100 ms and releases over 40 ms small room echo at 60 ms, 22% wet
