Five Nights at Treasure Island is a fan-made horror game inspired by Five Nights at Freddy's, built around a distorted, abandoned version of Oswald the Lucky Rabbit and other classic cartoon characters. Oswald's jumpscare became one of its most recognisable moments as gameplay videos and fan edits circulated on YouTube, where the sudden scream was clipped, remixed and shared on soundboards. It remains popular with FNaF fans because it mixes familiar cartoon nostalgia with an unexpectedly harsh horror payoff, making it easy to reuse in memes, edits and reaction clips.
