Place this clip right after the missed move in the edit, then follow it with the Roblox Oof for the crash landing. For a longer sequence, build tension with a chase clip first and save this as the closing beat of the fail.
About this sound
This five-second clip captures C00lkidd's Walkspeed Override failing in his Milestone 4 form, with the in-game fail reaction that plays when the speed move does not land. It feels frantic and deflated at once, like confidence collapsing into a stumble, which is why the moment reads as funny rather than threatening. It comes from the Roblox horror game Forsaken.
