The episode begins with SpongeBob cooking Krabby Patties, until he sees a loose thread on Squidward's shirt. He wants to pull it, and Squidward allows him to do so, but only if he lets him read his book in peace. SpongeBob starts unraveling many things at the Krusty Krab, including a very high-value dollar of Mr. Krabs', causing him to become poor.
SpongeBob continues unraveling things that annoy the citizens of Bikini Bottom, especially Squidward who always has his clothes unraveled by the string. Eventually, SpongeBob unravels the entire universe, only to have him get unraveled by Patrick, who uses the string as dental floss, ending the episode.
