The episode begins at the Krusty Krab, when while SpongeBob is cooking, he sees a loose thread on Squidward's shirt. Squidward asks SpongeBob only to pull the string if it will not distract him from reading, and so SpongeBob does. The string unravels Squidward's shirt, rendering Squidward naked. However, the string does not end, and it starts to unravel other citizen's clothing, money value of Mr. Krabs' $100,000,000 bill, and even elements of buildings. A cab tugs on a string, causing it to unravel and disappear. As Squidward is also finding new shirts, the string keeps unraveling them. SpongeBob also unravels Sandy's tail and the outline of the treedome, causing it to break, forcing Sandy to frantically swim to the surface.
At the zoo, Bubble Bass tricks sea monkeys off a Krabby Patty, but the string unravels the bars and allows the monkeys to attack Bubble Bass. Eventually, SpongeBob manages to unravel all of Bikini Bottom, but finds out that the string leads to a fisherman. Despite that, SpongeBob still manages not only to unravel the fishing rod, but also the fisherman. SpongeBob unravels the Bikini Atoll, and then the whole universe, leading to only a white dimension, ending the string. When Patrick appears, he finds a loose string on SpongeBob's shirt, unraveling SpongeBob and making him disappear, while Patrick uses it as floss as the episode ends.
