Place it in the middle of a short edit, after the setup and before the reaction shot. Follow it with the Run Vine sound effect for a quick escape attempt, then close with the Nope meme sound to underline the defeat.
About this sound
This is the original Roblox death sound, a brief human-like grunt that lifts a little and then lands on a soft, cartoonish oof, lasting well under a second. It feels funny and instantly familiar, more like a playful stumble than a serious loss, so listeners tend to smile rather than wince. It was the default sound when a Roblox character was eliminated in the game's early years.
