Place this clip right at the loss of balance, then follow the landing with a vine boom sound for extra impact or a spongebob fail sound if the character stays down. Use it before a reaction cut, not during dialogue, so the pratfall stays the focus of the sequence.

This is a short cartoon slip and fall effect built around a banana peel gag, with a quick sliding squeak, a tumbling tumble and a soft comedic thud at the end. It feels light, silly and instantly embarrassing in a harmless way, turning a simple loss of balance into a slapstick moment viewers recognise before the fall even lands.
