A short hollow bonk: a woody low tone that drops fast, with a hard wooden knock on top. Use it for cartoon collisions, a character walking into a door, a mallet hit, or any impact that should sound funny rather than painful.
knock: white noise 12 ms, band-pass 900 Hz, Q 1.8, full level at onset body: sine 498 Hz -> 118 Hz over 140 ms (380 Hz of drop on top of a 118 Hz floor), 22 ms time constant (about 150 ms to -60 dB) low-pass 3.2 kHz so the knock stays wooden, not hissy soft clip (tanh 1.6) to make it hit harder no reverb, nothing after 180 ms
