On a trip to the zoo, Team Mystic encounters plenty of rare Pokemon. Then Gianna loses her lucky Pokemon-catching cap, and their fortunes take a turn for the worse. Suddenly, there's not a Pokemon in sight, and the friends have to stop throwing Poke Balls and start searching the zoo for Gianna's favorite cap.
