Old Ladies

The Old Ladies (also known as Old Women) make their first appearance in "The Enchiridion!," where they are destroyed by Gnomes. Seconds after seeing them destroyed, Finn retreats to a stream in depression because he couldn't save them. Jake then tells Finn that they were just illusions, and that Mount Cragdor was designed to mess with Finn's head. The first two Old Ladies that were supposedly destroyed are seen at the picnic at the end of the episode, along with Mannish, Key-per, and Princess Bubblegum (who is using a hologram transmitter). They disappear when Finn jumps into the sky at the end of the episode.
