Worms

Worms are creatures in the television series Adventure Time. They first appear in the episode "Tree Trunks," where they make a brief cameo in an attempt to eat an Apple. In the episode "The Enchiridion!," there are worms in the trees as Finn and Jake were riding the giant dollar. The Worms also appear in the show's closing credits. They are later seen in "Evicted!." A worm first appears on Finn's bed, and makes some kind of siren-like noise, which went somewhat like "Wawawawa". Finn threw The Enchiridion at the worm to knock it off. Later, when the boys are given their house back from Marceline, they find it is infested by many Worms, perhaps the reason Marceline gave them back their home, including the Giant Worm King. It is believed that when they are seen by someone, they give off the siren, supposedly to signal or call the Giant Worm King. They may also have the ability to hypnotize others (at least) into hugging them.

A subspecies of Nerd Worm appears in The Real You.

Appearance
All these worms are small and green with stripes running down their body. They also look similar to their king, except much smaller, may not be able to talk, and don't have a small crown on the side of their head. Their appearance and movement resemble that of inchworms only with rounder heads.
