Put it at the start of a fall sequence, after Cartoon Chase Music has set up the chase, then follow the drop with a reaction sound to close the gag and keep the edit moving.

This is a 104-millisecond descending piano glissando, a rapid slide down the keys with a bright, cartoonish tumble. It feels sudden and silly, like a pratfall in sound, landing with a quick comic thud of momentum. The clip comes from Mickey Mouse Mixed-Up Adventures, where that kind of brisk musical fall punctuates a visual gag.
