Mudshark sees everything. Nothing gets by him. He always knows where to find things (courtesy of his little sisters!). But when the principal starts making weird announcements--a missing gerbal, missing erasers, and something strange in the faculty restroom, where the custodian reports every day with heavy duty equipment--something is up, and Mudshark can't figure it out. Plus, there the parrot in the library, who knows things too. Maudshark's school is weird to start--magicians, animal experts, scientists who sometimes need hazmat crews--but something's going on, and Mudshark has decided to stop it.
This is funny. I like it.
Suggestion: go to the library and search titles until you find Mudshark!
