Aquandrius

The Mud Eel is a long, wish granting creature that appears in "The Limit." He is named Aquandrius in his character design document. He is a muddy serpent of sorts that administers small magical orbs that grant wishes to those that find the center of the maze. When Finn uses the Ancient Psychic Tandem War Elephant to help him and the others escape, the Mud Eel becomes furious, stating that they were supposed to die, not get their wishes granted.
