Place it at the exact moment a rescue or reveal lands in your edit, then follow it with a Pop Sound Effect to close the beat. Keep it near the end of a rescue sequence, after the build-up and before the next scene, so the payoff stays clear.
About this sound
This is the bright, chirping squeak a Grub gives when the Knight frees it from its glass jar in Hollow Knight. The quick, bubbly burst feels joyful, grateful and childlike, like a tiny celebration after a small rescue. It comes from Team Cherry's 2017 Metroidvania, where 46 Grubs are hidden through Hallownest and freeing them earns rewards from the Grubfather.
