Timmy Failure - It's The End When I Say It's The End

Though I, Timmy Failure, have solved many notorious crimes and now wish to enjoy my retirement, my fans have begged me to turn my memoirs into a movie, an ode to my greatness. I am, however, beset by enemies, the worst of whom is Tom John John, the buffoonish movie director.
What’s more, my father is in town, working at a bar, which is obviously just a cover for our father-son crime-fighting partnership. And my dim-witted polar bear business partner, Total, wants to be reunited with his family. I should have known it would end like this. I expected more.
