PlotAfter learning how difficult growing their "Smell-of-Death Vine" (Vitis Odor Mortis) for school is, Randy and Howard decide to use all the water/food for the plant at once. A week later, the plant is dead, and the two are panicking. Howard then comes up with the idea of using the Nomicon in order to bring the plant back to life to avoid being grounded due to their soon-to-be bad grade. The two then debate why they have different costumes for the Whoopee World Frightacular (Randy being the lower half of a cow, and Howard as Viceroy). After skimming the instructions, Randy attempts and fails to restore the plant.
While Mrs. Driscoll is grading the plants, her husband's skeleton comes to life and kidnaps Howard, saying, "Doomsday is coming!" The Ninja then attempts to fight Jerry Driscoll; he throws Ninja Rings, but they are useless as they pass through Jerry's ribcage, while Jerry counter-attacks by throwing his rib-bones and the school’s pumpkin decorations. Randy slips on pumpkin goop, tumbling down the stairs, and Jerry takes this opportunity to escape. The Ninja then returns to the science classroom and asks Mrs. Driscoll what Jerry would want with Howard. She then explains how her husband had long ago created a Doomsday Device, and was then betrayed by Viceroy, who had him (Jerry) arrested.In his lair, Jerry starts to finish his Doomsday Device, and discovers he kidnapped the wrong person. Meanwhile, Viceroy is visited by the Ninja. Viceroy then agrees to help stop Jerry upon learning he's alive. He then explains that Jerry only built the device to get Valedictorian in his college class at M.S.U. (Mad Scientist University). The two and Mrs. Driscoll then discover Jerry's base under Mount Chuck's Gift Shop. At Jerry's base, the Ninja fights Jerry, while Viceroy tries to deactivate the now-active Doomsday Device. However, they are both unsuccessful, until Mrs. Driscoll arrives. After the Ninja kicks off Jerry's head, Jerry and his wife discuss the necessary results of the device's functioning — they would be apart forever). Jerry at last deactivates the machine, only to begin planning an even more destructive device. Deciding he's too dangerous to be kept alive, the Ninja reverses the resurrection power used on Jerry. Once out of the building, Howard asks Mrs. Driscoll to bring up their science grade; she grudgingly gives them a C.
Back at the school, Randy and Howard see Mrs. Driscoll dancing with her husband's skeleton in the Science Lab and decide to go to the Frightacular. As the two depart, Howard points out how strange it was that the resurrection power affected only Jerry, when the science class was crammed full of dead lab specimens; unbeknownst to the boys, cadavers on all sides spring to life.
