Toadblatt's School of Sorcery: In a parody of the Harry Potter series, Grim sends Billy and Mandy to a sorcery school so the latter duo could avoid boring summer camps they were supposed to go to. The sorcery school is owned by Dean Toadblatt, an anthropomorphic frog. Billy and Mandy are sent to the most hated house on the school, Weaselthorpe, while Grim becomes a prefect for a more loved house, Gunderstank. Billy and Mandy team up with boy wizard Nigel Planter to sabotage Gunderstank. Planter takes all the credit for the sabotage (which was Mandy's idea), but he is punished once he is found out by Toadblatt. Educating Grim: Billy and Mandy take a reluctant Grim to school with them. Mandy's nemesis, Mindy, befriends Grim to annoy Mandy and Billy calls for their other friend, who is Abraham Lincoln. Mandy devises a plan in which Mindy ditches Grim, and keeps Abraham as her friend instead. It's Hokey Mon!: After watching Billy and Irwin play with their "Hokey Monsters" cards (parodying the Pokémon Trading Card Game), Grim makes the monsters come to life. Soon, all the other kids want their own cards to be real too, and the city is soon under attack by a multitude of Hokey Monsters. To put an end to the mayhem, Mandy draws her own card, Mandy's Monster, which defeats all the other monsters by turning them into toast.

Night of the Living Grim: Grim is lying sick in bed with "Encroaching Doom Syndrome". The Underworld doctors are not able to help Grim, and he becomes a human being. Back in Endsville, Grim seems attractive to women, but he ends up being punched by jealous boyfriends, especially Billy's dad Harold. Grim covers himself in the mucus that he produced when he was sick and becomes a skeleton again, and Billy tries it too. Brown Evil: Part 1: Taking inspiration from his Pat the Baker video game, Billy decides to bake chocolate brownies. Billy uses "Evil Powder" from Grim's old trunk instead of salt, and the resultant brownies stink. Mandy tells Grim to get rid of the brownies, and he reluctantly does, but he also stores some of them in his skull. Soon, the stench of the brownies spreads through the world and starts resurrecting dead people, animals, and even food, as zombies. Brown Evil: Part 2: Billy and Hoss Delgado, spectral exterminator, team up to destroy all the zombies that congregate outside the house, but the zombies reassemble into a bigger zombie. Delgado realizes that the zombie is after the brownies that Grim has in his skull, so Delgado and Grim battle furiously for them. The zombie eats the remaining brownies and falls apart.

In the distant future, Mandy has turned herself into a giant worm-like creature to be immortal, and now rules the whole world. Mandy gives false information to a clone of Billy to capture the members of a resistance that try to defeat her. The episode parodies the science fiction novel God Emperor of Dune by Frank Herbert. Creating Chaos: When Billy, Mandy, and Grim go fishing, Eris, the goddess of chaos, gets Billy to help her use the Apple of Discord to create chaos (after her father grounded her). Instead of using the apple, Billy becomes distracted with his own idiotic errands, leading Eris to go insane. Billy finally decides to start creating chaos, but Eris is already too altered that she runs away. The Really Odd Couple: Billy accidentally sets off a powerful stink bomb in Mandy's house and, while the house is being disinfected and fumigated, Mandy's family goes to live with Billy's.

Grim warns them about the ghost of Mrs. Doolin, a lady that lived there. Mandy dares to go inside to retrieve the dice, and she befriends Mrs. Doolin, who is alive and well, and who says that all the stories told about her (that anything that went beyond her fence into her garden never came back) are inventions from Grim, whom she beat long time ago at a staring contest. Fearing for Mandy's life, Billy also ventures into the house, but Mrs. Doolin and Mandy scare him away by posing as ghosts. It appears that Mrs. Doolin is in fact a ghost, and when she meant "beating Grim", it meant that she "beaten death". Tween Wolf: After when Grim fails to pull a werewolf out of his hat, Irwin is bitten by said werewolf. Billy takes Irwin as his new pet dog, naming him Sprinkles, and enters him in the Endsville Dog Show to compete against Mandy's dog, Saliva.

Mandy easily wins the tournament and does not care about the money anymore, only about fighting. It turns out Kuan Ti is actually Eris in disguise, and this was just another of her schemes to create chaos. Seeing how he has a chance to get rid of the kids and finally be free, he tries to take advantage over this by making Billy a superb fighter too, so he and Mandy can fight ferociously to the death until the entire arena is destroyed. With both still alive, Mandy still demands the prize money, which she uses to buy Hector Con Carne's Bunny Island.

In the following, Billy and Yap-yap continue eating junk food, so Mandy suggest to use the antidote to the original remedy.

To stop Jack from carrying on with his vengeance, Mandy sets up a series of pranks for him.
