World of Goo is an independent puzzle game developed by 2D Boy and first released in 2008, built around guiding living goo balls to a pipe in each level. The clip is catalogued as a Timebug spawn sound, and its short chirp became a recognisable cue for players familiar with the game's quirky cast. As gameplay clips and short edits spread online, the one-second effect travelled beyond the game itself, often reused as a cute, low-key pop for arrivals and reveals. It endures because it is instantly tied to that quirky, hand-crafted world without needing any explanation.
