Timmy is excited for the weekend, until his parents announce they'll be away on a "business" trip for the whole weekend, and leaving him with Vicky. Timmy then wishes for something to take Vicky a million million miles from here. Cosmo then travels to Yugopotamia, where Mark is having his substandard birthday party. He leaves in disappointment, mourning over losing Vicky. Cosmo then appears in front of Mark and produces a forged message from Vicky. Mark and his friends, Jeff and Eric travel to Vicky's house on earth via his spaceship, and kidnap her after using a weird spray to knock her unconscious. The threesome then convince Mr Turner that Vicky is going to Europe. Timmy is confident that they'll have to cancel their trip, but they have a plan B. They drop him off at Flappy Bob's Peppy Happy Learnatorium, where he is annoyed by Happy Peppy Gary and Happy Peppy Betty. He comes across a Smack-a-Mole game, which Gary and Betty keep him from playing and instead make him watch a movie on the mole and its extinction. A fed up Timmy wants to go home, but has to stay until Vicky returns from Europe, but Timmy says shes never coming back. Gary and Betty are ecstatic that Timmy will be here with them forever. Panicking, Timmy runs away from them and wishes that Vicky was back, but cannot because Mark is in love with Vicky and magic can't undo true love. Timmy then wishes himself, Cosmo, and Wanda to Yugopotamia. The Yugopotamians are frightened by Timmy's appearing on Tugopotamia. MArk returns with Vicky and refuses to give up Vicky and challenges Timmy to a battle to the death. For the first round, he chooses the Yugopotamia War Arena to battle him in. Timmy wishes Cosmo and Wanda into high tech space weapons, which shoot pillows at Mark, because Yugopotamians hate good and nice. But Timmy is then disarmed and Mark prepares to zap him out of existence, but surprisingly he misses, leaving a big donut shaped hole in the ground around Timmy. Timmy is now able to choose the Arena for the second round. To his advantage, he chooses Flappy Bob's Learnatorium, (as Gary and Betty were still trying to find Timmy) where Mark is horrified by the sight of everything there, including the children who tell him that he has a "funny head". Timmy wins the battle fair and square, and they give Vicky, still unconscious, back to him. He decides to spare Mark's life, and gives the Smack-a-Mole machine with Gary and Betty inside, but is still made sick by them.
Back in Timmy's house, Timmy is happy that Mark's gone, Vicky's back, and he's not stuck at the Learnatorium. Vicky then wakes up and starts yelling at Timmy, who knocks her unconscious again with the weird spray from earlier.
