Put it at the very start of a Grimm encounter, just before the fight footage begins, then follow it with a boss sting to carry the scene into the battle. For a comic cut, pair it with a short villain laugh before returning to gameplay.
About this sound
This short Hollow Knight clip catches Grimm, the crimson troupe master, letting out his quick, theatrical 'Hooseh!' It feels playful and slightly menacing, like a showman announcing himself before a trick. The sound comes from Hollow Knight, where Grimm appears as the leader of the travelling Grimm Troupe.
