In a remote island facility, Professor Marlowe Cragis and his team of researchers are working on the answer to global overpopulation: half-size humans with a smaller appetite, of course. But the experiment goes awfully awry when the scientists accidentally create a race of giant, venomous shrews. As the shrews run out of animals to eat, they begin to feast on human flesh! Who will be the last to survive?
Meanwhile, Joel presents Crow with a fresh pair of J.C. Penney dress slacks, the Bots invent the new Killer Shrew board game and sugar-intense drink, and end the day by attacking Joel while dressed as shrews.
