Author/illustrator Nick Bruel tries to explain to the reader how to write a story, but Bad Kitty is not at all happy about the plot, which has her going on a turnip diet to lose weight. Includes a recipe for roasted turnips.

It is time for the Stermont Derby, a race around downtown Stermont in homemade vehicles, and Alexander, Nikki, and Rip are planning to compete, but so is a new monster, a Speedah-cheetah--and in addition to a diet of rotten eggs it plans on eating the race losers, especially the members of the Super Secret Monster Patrol.
