    Created by New York Times best-selling cartoonist Stephan Pastis.Take eleven-year-old Timmy Failure — the clueless, comically self-confident CEO of the best detective agency in town, perhaps even the nation. Add his impressively lazy business partner, a very large polar bear named Total. Throw in the Failuremobile — Timmy’s mom’s Segway — and what you have is Total Failure, Inc., a global enterprise destined to make Timmy so rich his mother won’t have to stress out about the bills anymore. Of course, Timmy’s plan does not include the four-foot-tall female whose name shall not be uttered.
