When the town librarian's cat goes missing, Ethan, Devin, Carlo, and Gianna grab their Poke Balls and Razz Berries and hit the streets to search for him. Along the way, they hope to catch a frisky Meowth, or even a legendary Mew or mythical Mewtwo. But Team Mystic's favorite Pokemon are just as elusive as the lost cat. Plus, someone or something is throwing the friends off track with misleading clues. Now the Trainers-turned-sleuths have to choose which clues to follow--and which Pokemon to catch. Can they use the knowledge and resourcefulness that earned their team its prestige to find both the real cat and the Pokemon they dream of catching?
