The Monster Pets cheer up a crabby apple tree, Phoebe and Mo-Mo look for a fuzzy ball, and Luna learns how to use her moonbow magic.

Molasses's painting keeps everyone guessing, the Monster Pets find treasure at the end of a moonbow, and Mo-Mo won't let Henri take a nap.

Phoebe finds a magical feather, Bubble and Trouble fetch food for a hungry Henri, and Molasses "runs" a slow and steady race.
