When Billy, Mandy and Grim go to a joke shop, they find the owner is former boy wizard Nigel Planter, who reveals that his powers diminished and was kicked out of Toadblatt's School of Sorcery. Planter steals Grim's scythe and heads to the school to exact revenge on those who wronged him. The guys seek the help of Planter's sworn enemy, Lord Moldybutt, to find the school. Grim recovers his scythe, and Moldybutt turns out to be in fact only a real estate agent, who informs Planter that he is the heir to the "Peanuts by Planter" farming company.
