David is jealous of Shane's pet fly, Fido, and decides that he wants a pet of his own. Puppet volunteers to play the role of his pet, but David says he thinks of Puppet more as a friend. David and Shane search for a pet shop in the Puppy Room, but there are no puppies to adopt. They later ask a parrot for directions in the Parrot Room, but the parrot just repeats whatever they say. The Schmuzzies make some rhyming suggestions about which pet David should get (all ending with "-oon"), which ends up opening a door to the Moon. In the end, David finds a pet shop run by Mrs. Foil, and he decides to take Mrs. Foil's chair home as his new pet: Spot the Chair.
