A chapter-book series spin-off from Inspector Flytrap by New York Times best-selling author Tom Angleberger! 

This hilarious chapter book mystery series stars Didi Dodo, the daring spy-in-training, and Koko Dodo, Didi's reluctant sidekick. In Robo-Dodo Rumble, Koko Dodo's cookie shop is facing some stiff competition from an evil robotic dodo (a Robo Dodo). The Robo Dodo is selling its cookies for only a penny! Why? To put Koko's shop out of business! And if that weren't bad enough, a giant sea monster starts destroying the town! But don't worry. Didi Dodo has a daring plan. 

From the mind of the inimitable Tom Angleberger, this wacky caper promises high-speed chases and big belly laughs. The book takes place in the same world as Inspector Flytrap but does not require knowledge of the previous series.
