Terraria is a 2D sandbox adventure game developed by Re-Logic and released in 2011, known for its exploration, crafting and boss battles across procedurally generated worlds. Pets were added as light cosmetic companions that follow the player without fighting, and selecting them from the equipment menu triggers this short interface sound. As Terraria clips and memes spread on YouTube and gaming soundboards, even tiny UI clicks like this became instantly recognisable to fans and started being reused outside the game as a playful selection cue.
