On Pirate Day at school, all the children dress up as pirates, and Pedro and his friends, Katie and JoJo, continue the theme in their clubhouse after school--but they all want to be the pirate captain.
Pedro is excited for his class's trip to the aquarium, but when he gets separated from the others near the shark tank, he gets frightened and starts running to and fro--until he takes a hint from the shark to stop going in circles.
Pedro collects a lot of different bugs for a class assignment, but when his brother lets them out in the house, their parents are furious, and ban any further collecting.
Pedro forms a new club with his friends dedicated to solving mysteries--and the first two assignments are finding his mother's locket, and his father's cell phone.
Pedro and his friend Katie Woo are both running for class president. Pedro knows he can do great things for his class, if only he gets past that speech!.
Pedro would love to be the goalie in the team's first game, but another boy is bigger--so all his friends come over to help him practice before the tryout.
