Cracking the Magikarp Code

Ethan and Devin have finally gotten the puppy of their dreams! Even better, taking their new pup to the dog park near the lake means the chance to explore a new Pokémon GO habitat!
But the energetic puppy chews on everything in sight, including a map she pulled down from a PokéStop. When they pull the ruined map from the puppy's jaws, Ethan and Devin are shocked to discover a mysterious code on its back. Is someone using the map to send secret messages about the best places to fish? Or better yet, to hunt Water-type Pokémon? Looks like a case for Team Mystic!
Fans of Pokémon GO will love putting the clues together—and cracking the code—in this compelling fourth book in the Unofficial Adventures for Pokémon GO Players series!
