Mason and Phil are fed up with the lemurs annoying them. They find out a solar eclipse is coming and tricked Julien by telling him the "sky spirits" are angry at him just as the moon covers the sun.

Mort quadruples in size after an accident with one of Kowalski's inventions, a super-ray designed to enhance fish. After finally realizing that Mort is super strong, Julien uses him to steal food and supplies from the other animals, like stealing an elephant's peanuts, Joey's (from Assault and Batteries) hay for Julien art work.
