A badly spelled message in a bottle addressed to Uncle Pirate appears at Wilson's front door, and Mom starts baking bad news pie—this can't be good. Uncle Pirate's formerly mutinous crew is marooned on an island! Though Uncle Pirate is loyal to his new crew at Very Elementary, he cannot desert his old shipmates and sets off to find them. But when he doesn't return, it's Uncle Pirate who needs rescuing! Wilson, Captain Jack the penguin, Ms. Quern the school secretary, and sneaky Principal Purvis set off in a blimp to save the day in this rollicking read that's ideal for adventurous young readers.
