Put it at the reveal, just as the horse or rider enters the frame, then follow it with clapping if the entrance lands or a fail sound if the boast falls flat.

This is a seven-second horse whinny performed as a vocal effect for Horace, the horse character, with a rising neigh that sounds playful and a little over the top. It feels goofy and lighthearted, like a cartoon animal showing off for attention. It comes from Moose Hunters, a Mickey Mouse cartoon released on 20 February 1937, where Vance Colvig performed the sound.
