Mayor Humdinger, and his kittens are going to the Pet Parlor to get baths. Katie explains that the Pet parlor closes at that time every day for lunch. Back in Foggy Bottom, Harold is looking for meteor chunks.
Mayor Humdinger comes up with an idea to build his very own kitty salon. He tells Harold to start construction of it. At The Lookout, the pups are playing mirror. Harold finds a meteor piece and gets his superpowers back. He builds a cloning machine in the Humdinger lair.
Mayor Humdinger mistakes the cloning machine for the kitty salon. He goes in and activates it, cloning himself. He then realizes that it is a cloning machine and tells the clones to go get tuna for the kittens. Harold follows to get them to do as he says.
The clones ask Mr. Porter for tuna, freaking him out in the process. Harold tries to get the clones to do as he says, but they tease him, and put him on top of the fruit stand. They then decide to take Katie's Pet Parlor to Foggy Bottom. They pick it up and start moving it, all while Katie and Cali are inside.
Katie calls Ryder, and tells him what is going on. He summons the pups to the lookout. He deploys Chase and Rubble. Chase finds a trail of building pieces. Ryder tells him to follow it. The clones see Chase catching up to them, and then start running faster. They get to the gorge and accidentally drop the pet parlor. It is now stuck in the gorge.
Katie and Cali are okay. Ryder summons Marshall to the scene. Harold, who has a clone-catcher-age with him, finds the clones, and tells them to do as he says. They refuse, and tell him to help them get the Pet Parlor before the pups do.
Marshall arrives and the pups charge up. Marshall goes into the gorge with his hover vehicle. He goes inside the Pet Parlor and Super-jumps himself, Katie, and Cali out of the gorge. Harold and the clones are almost at the gorge.
Rubble does a ground shake, and Harold looses the meteor piece. He and the clones are now trapped in the clone-catcher-cage. Chase uses his sonic bark to get the pet parlor out of the gorge, and Rubble catches it. Katie thanks them and promises them super bubble baths.
Rubble carries the pet parlor back to where it belongs. Later, Harold puts Mayor Humdinger and the clones back into the machine, much to Mayor Humdingers dismay. Harold runs the machine, and then only Mayor Humdinger comes back out. The kittens destroy the machine.
