Jeffy has to do summer school at home since he failed!
On the last day of school, Jackie Chu is giving the kids report cards. Junior gets his report card first, with all D's. Cody tells Junior that he was going to fail on purpose for more school but he doesn't. Next, Cody gets his report card with all A+'s. Then Jackie Chu gives Jeffy his report card then finds out he fails. Jeffy says he passes then Bully Bill tells him he fails then bullies him. Jeffy comes home from school and tells Mario and Rosalina that he passed. He tells them that he got B's instead of F's.
Mario calls Jackie Chu then Jackie Chu tells him that Jeffy failed and he has to do summer school at home since Jackie Chu is going on vacation. The doorbell rings and Mario answers the door. Jackie Chu brings stuff for Jeffy's summer school. Even though Junior got all D's, he doesn't want to show his dad his report card.
Cody was upset about his grades because he got all A+'s. Junior and Cody has the idea to sneak into the classroom and change their grades so Jeffy doesn't have to go to summer school. Jackie Chu tells Mario to teach summer school for him. Mario calls Jeffy for summer school. Jeffy draws himself then does his "Doodle doodle pencil fart" so he doesn't have to do summer school. Mario asks Drawing Jeffy some simple school questions, such as 2 + 2. Drawing Jeffy starts going crazy.
Junior and Cody go inside the empty classroom then goes to the computer. They find out that the computer has a password and try to guess it. They guessed the password and logged in. Jackie Chu was about to go inside and Cody changes their grades. As Jackie Chu went inside, Junior and Cody hid underneath his desk. Jackie Chu goes to his desk and finds out that someone logged onto his computer. He finds out that Jeffy's grades went from F's to B's. Junior pretends to be Jackie Chu's grandfather, talking to him from heaven and telling him to go to the Great Wall of China. Jackie Chu leaves the classroom.
Mario tells Drawing Jeffy that he'll have to repeat 2nd grade if he fails summer school because he wasn't taking it very seriously. Jackie Chu calls Mario and tells him that he made a big mistake about Jeffy's grades and tells him that Jeffy passed. Mario is very happy that Jeffy passed, and decides to take him on vacation with him, and Rosalina, but Mario is unaware he took Drawing Jeffy instead of the real Jeffy.
Back in the play room, Junior gives Jeffy his changed report card to give to Mario. However, Junior did not give Cody his changed report card, much to Cody's sadness. Cody decides to take Jeffy's blue balls drawing, and leaves. Jeffy goes into the living room to show his report card to Mario, and go on vacation. However, Mario has already left with Drawing Jeffy, and the video ends with Jeffy looking for Mario, unaware that Mario has left.
