Slime Rancher is a first-person ranching game developed by Monomi Park and released in 2017, where players collect, feed and breed colorful slimes on a distant planet. Each slime type has its own happy vocalizations and movement sounds, and the short bounce became a favorite clip outside the game because it captures the creatures' squishy charm in less than half a second. Fans share it in edits, streams and soundboards as a universal cute boing, used whenever something round, soft or cheerful hops on screen.
