The King Worm is the king of Worms in Adventure Time. He makes his first appearance near the end of the episode "Evicted!". He hypnotizes Finn and Jake to hug him, by using green beams of light that shoot out of his eyes. This hypnotizing ability is something that all Worms of this species can do. However, only the King Worm's beams seem to have any effect. He makes another appearance in the eponymous episode "King Worm" which is a continuation of what happened when the boys got zapped by him. King Worm uses that beam to trap his victims in a dreamscape prison where he tries to either trick them into staying or freak them out long enough to drain them of their life energy. The only way to break free is to have your deepest fears appear on the dream plane, this causes the realm to destabilize and reverses the process of the energy drain. After breaking free, Finn tells him to get out of their house and he slinks away drained and almost shriveled up.
