Spy next door

On a school field trip to the museum, Dexter puts his brand-new super-secret spy skills to the test when someone has broken into the Egyptian exhibit to steal Pharaoh Hun-Ga-Re's greatest treasure: a sacred sandwich that can raise the dead. But who could be hungry enough to want a six-thousand-year-old snack? With an army of robot ninjas, a mustachioed mystery man, and a sneaky new classmate lurking around every corner, it's up to Dex to find the petrified hoagie first and save the world from a monstrous mummy's ancient curse.

"Third-grader Dexter Drabner dreams of being a skateboarding-hero-spy, while contending with his nemesis at school, Millicent the bully--and when science teacher Mr. McFur's prized lab rat, Pretty, eats a piece of radioactive gamma broccoli and grows to the size of an elephant, he gets his chance to save the school from destruction"--OCLC.
