| Please note the following:
"Jeffy's Dog!" is the 338th episode of SML Movies.
The episode starts with Mario sleeping, then Jeffy wakes him up asking if he can go outside with Pee Pee Suck in which Mario says yes. So Jeffy decides to play hide and seek with Pee Pee Suck and she ends up rolling away.
Rosalina asks Mario if he wants to get dinner tonight. Mario then says he needs to get a babysitter for Jeffy. Much to Mario's surprise, Rosalina says Jeffy isn't in the house. Mario then remembers that he said that Jeffy can go outside. Both get worried and go outside to find Jeffy. They call for Jeffy and then they find him behind a fire hydrant. They go to Jeffy, but Jeffy tells them to be quiet because he is playing hide and seek with Pee Pee Suck, who is the seeker. Mario says that he doesn't see Pee Pee Suck. Jeffy complains to Mario that he gave away his hiding spot and Pee Pee Suck is going to find him. Mario says that he wasn't allowed to bring Pee Pee Suck outside, but Jeffy said that Mario actually did tell him that he can bring him outside. Mario says again that he doesn't see Pee Pee Suck, then Jeffy begins to cry. They got Jeffy to stop crying and banging his head against the fire hydrant, and they all go look for Pee Pee Suck. They try searching for her outside, but Mario says that she could be inside. They looked everywhere, but no luck. Jeffy was about to cry, but Mario stops him and says that Pee Pee Suck could be upstairs, but then Jeffy interrupts him by screaming.
They go upstairs, but still no luck. Jeffy says that if they find Pee Pee Suck, he will pull his arm off. Jeffy attempts to pull it off, but Mario tells him to stop, though Jeffy persists in pulling off his arm. Rosalina suggests getting Jeffy a new pet, but Mario refuses. Rosalina says that Jeffy can get a dog, and inside dog. Mario says that Jeffy's hamster was an inside hamster, but he took it outside. Rosalina begs Mario to get Jeffy a dog, and Mario even says that he let Jeffy name his hamster Pee Pee Suck. Jeffy says that he is making progress as he heard a snap. Mario finally lets Rosalina get Jeffy a dog, a nice one. He then tells Jeffy to stop trying to pull his arm off, and that Rosalina is coming back with a surprise.
The scene then cuts to Mario hanging up a lost pet poster of Pee Pee Suck. Brooklyn T. Guy, who was dressed up as an officer, comes to Mario, wondering about Pee Pee Suck being missing. He then explains to him that he has been missing a pee pee suck since he got married, which wasn't the pee pee suck that Mario was referring to. Mario says that he recently got married, which Brooklyn T. Guy felt sorry to hear. Mario tells the officer that his son's hamster is missing, and that his hamster's name is Pee Pee Suck. Brooklyn T. Guy says that he wouldn't let Mario hang out with his kids. Mario asks if he can help find her, but Brooklyn T. Guy responds by saying that he doesn't look for lost animals, just lost people. Then he gives Mario advice by saying that he should put his contact information on the poster.
Mario then returns to the red couch, sitting next to Jeffy. Rosalina notifies Mario by whispering to him that she got Jeffy a dog. She brings the dog to him, which appears to be choking and gagging, leaving Mario concerned. Rosalina says that the dog is paralyzed, and that she got him from the shelter. Rosalina also says that she paralyzed him on purpose so that he can't run away. Mario then shows Jeffy the dog. Jeffy gets excited, then Mario asks him what to name him. Jeffy wants to name the dog "Sh*tass". Mario disallows that name. Sh*tass then poops, which disgusts Mario. Jeffy asks Mario if he can take Sh*tass for a walk. Rosalina says that it is good exercise. Mario asks how he can take Sh*tass for a walk as he is paralyzed. Rosalina says that he can try it out.
The scene cuts to Jeffy with Sh*tass on a leash while laying in the road. Jeffy tries to take him for a walk, but instead drags him. Rosalina says that is sweet, while Mario says that is messed up. Then, Sh*tass poops again, but off-screen.
They go back inside, with Mario, Sh*tass, and Jeffy on the couch. Jeffy loves Sh*tass so much, but Mario tells him to stop calling him Sh*tass. Jeffy then wonders if Sh*tass knows any tricks. Mario doesn't think so. Jeffy then tries to play fetch with Sh*tass by grabbing a tennis ball and throwing it. Mario says Sh*tass can't play fetch as he is paralyzed. Jeffy tells the dog to roll over, but Mario says that he can't roll over either. Jeffy then tells the dog to stay, but Mario says that he can't stay, or maybe can. Jeffy wonders why Sh*tass is paralyzed. Mario responds by saying that he probably got run over by multiple cars, and his owner got rid of him. Jeffy then asks who got rid of Sh*tass. Mario says that Michael Vick maybe did. Jeffy then does his "Uh!" noises while Sh*tass repeats him. Sh*tass then poops again, and then the doorbell rings. Mario goes to the door while Jeffy hugs Sh*tass.
The person at the door was Officer Brooklyn T. Guy with Pee Pee Suck inside her ball. Brooklyn T. Guy explains to Mario that he saw Pee Pee Suck rolling down the road, and he pulls him over for being cute in a not cute zone, and he had to arrest him for jayrolling, which is like jaywalking but Pee Pee Suck was rolling in her hamster ball. Mario says that they just got Jeffy a dog, and doesn't want too many pets. Brooklyn T. Guy says that he never had a pet. Mario then gives Pee Pee Suck to Brooklyn T. Guy.
Then a COPS episode comes on, with Tyrone being arrested by Brooklyn T. Guy and Pee Pee Suck. Brooklyn T. Guy then tells Pee Pee Suck to cuff him, but rolls around, ending the video.
- This episode reveals that Logan still has Melvin.
- However, Logan said before that he sold Melvin, he later died. So this may be a new hamster or one of his friend's hamsters.
- The "Cops" TV show (parody of the real show) makes a second appearance. Its first appearance was in "Root Beer!".
- This video marks Melvin's third and final appearance.
- This video marks the second time Tyrone wears his "zebra" costume, which is actually a Prison Inmate costume. Its first appearance was in the video "Joseph's Mom!".
- This is the first SML video of November 2017.
- This is the first appearance of Sh*tass.
- This video was age-restricted at one point, but the age-restriction was taken off.
- There's a deleted scene of a montage where Mario, Rosalina, and Jeffy searched for Melvin, it was cut due to Logan not liking it.
- Jeffy naming his dog Sh*t*ss could be a reference to Dumb and Dumber where Hairy shows Lloyd his cat and named the cat Butthole.
- In this episode, the hamster is named Pee Pee Suck, but the hamster's name is Melvin and Jeffy's old fish was named Pee Pee Suck. Jeffy would normally call Melvin “Pee Pee Suck 2”. However, it is also possible that Jeffy forgot about the original Pee Pee Suck, or Pee Pee Suck 2 is now just called Pee Pee Suck due to the original no longer being around after Jeffy gobbled him up.
