This is a general sound effect rather than a quote tied to one famous scene or character. Short squeaky toy noises have circulated for years in meme edits, pet compilations, gaming videos and reaction clips because they are instantly readable and funny even without context. Creators keep using them as a clean alternative to louder gag sounds like a pop sfx or the Doge bonk when they want a softer, more playful payoff. Its staying power comes from how well it fits pets, rubber objects and anticlimactic visual jokes.
