"Wally and his human friend Henry have passed the test. They are now officially Puppy Pirates--and just in time for an exciting new adventure. A treasure hunt! The puppies sail to a deserted island with treasure map in paw, and ready to dig. But uh oh! This island isn't deserted after all..."-- Provided by publisher.

Captain Red Beard is too sick to organize the Pirate Day party, so it is up to Wally and the other pirate pups to get things ready--the trouble is that the Captain is very particular, and Wally has lost the decoder that would let them read the instructions.
