Milo Murphy's Law Wiki

"The Dog Who Knew Too Much" is the twenty-fourth episode of the second season of Milo Murphy's Law.

Diogee gets himself into a mission with Perry when he accidentally swallows a cookie-shaped jump drive that enemy agents are after. Meanwhile, Doofenshmirtz builds an Inator which makes picking up clothes around the house more convenient.


While Milo, Zack, and Melissa are on a crab boat for extra credit, the captain loses their forms, the backups, and goes over board himself. Diogee arrives, and Milo tells him to go home, which he begrudgingly does in a dingy.

He makes his way to the Museum of Sharp Objects as they have a toddler talent show going on. In the museum, Agent P is undercover on a mission.

At the Murphy Residence, Brigette scolds Sara and Doofenshmirtz for leaving their dirty clothes lying around the floor and tells them to clean up. Doof leaves to invent something to help them.

At the museum, Major Monogram tells Perry two enemy agents, Igor and Vlad, will be exchanging a flash drive disguised as a cookie when they are dressed as mother and child and to take it and deliver it to Harry Hamster's. Agent P finds the enemy agents and wrestles with them, but the flash drive quickly rolls away and Diogee finds and eats it.

At the Murphy's house, Doof creates a robotic hamper to take the clothes to the laundry room. After a brief malfunction it works, but it takes the clothes to Doof's old address.

Meanwhile, Vlad and Igor try to get the flash drive back from Diogee as Perry defends him.

The Hamper runs into the town as Sara and Doof chase it.

Back with Diogee and Perry, he defends the dog and lose their pursuers in an alley when their path is blocked by runaway circus elephants accidentally caused by Martin getting a latte. They are found but run away and run into and stop the hamper-inator. Sara and Doof trap it in a trash can and high five before Sara demands it back as it is Doof's fault.

The dog and platypus run and sit on a bus as Vlad and Igor steal an old woman's school, who beat them with her cane. The pair make it to the restaurant.

At the Murphy house, Sara and Doof return but Doof's nose hits the self destruct button and it explodes. Brigette is angry and Sara leaves in frustration while Doof goes for a walk.

At Harry Hamster's, the animals are chased by the humans until Perry ties them to a rocket ride. He meets the informant and tells him Diogee ate the drive and Agent P waits until it comes out. Perry walks him home and Diogee thanks him. Milo and company return wondering why they were on the crab boat in the first place. The captain return with their forms only to be washed away.
