A siren-like fart which is just like a fart, but can make different noises. Just classified at a much stronger frequency. A fart that changes pitches mid-fart.

A Grille Chompa is an enemy found in Clanker's Cavern, Mad Monster Mansion (inside Loggo), Rusty Bucket Bay and in several areas around Gruntilda's Lair. This bizarre fish- or slug-like enemy hides within broken grates on walls in damp and dark areas. If Banjo and Kazooie get too close, the Grille Chompa will growl and lunge from its hole, biting at the air three times before retreating back. It will continue to do so until Banjo and Kazooie move away from it or until it is defeated.
