Worms are creatures in Adventure Time. They first appear in the episode “Tree Trunks,” attempting to eat an apple. The worms also appear in the show’s closing credits. They are later seen in “Evicted!” A single worm appears on Finn’s bed, and makes a siren-like “wowowowo” noise. Finn throws The Enchiridion at the worm to knock it off, saying, “No worms on the bed!” Later, after Marceline gives Finn and Jake back their house, they find it infested by many worms, including the King Worm. It seems that they give off the siren whenever someone sees them, possibly to signal or call the King Worm. It is unknown whether small worms have their king’s ability to hypnotize others (at least) into hugging them. A worm also appears in “BMO Lost” dancing with other insects. A Pupil Worm appears in the episode “The Real You,” which shows some resemblance to the regular worms.
