Timmy Failure: Now Look What You've Done: Timmy Failure, Book 2

Timmy is about to crack the biggest case of his generation: A school competition to find a stolen globe. But someone is clearly trying to con the system. So it's up to Timmy Failure, with the dubious help of Total, his lazy polar-bear partner, and his unlikely new ally, eccentric Great-Aunt Colander, to find a way to defeat this injustice. If he can only get his entry form in on time.
