A collection of four separately published stories featuring Pedro, Katie Woo's classmate and friend.

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.

Join Pedro for his latest adventures with his pal Katie Woo. One day, he's pretending he's a pirate, sailing the high seas. The next day, he's practicing his karate, being as fierce as a ninja star. But no matter what adventure Pedro's having, he's always Pedro the Great! --Amazon

Something in Miss Winkle's classroom smells really bad, and when the class bully declares that it must be the new boy, Pablo, Pedro steps in to defend him--but the class still needs to know what is causing the stench and dispose of it.--

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.

From the creator of Katie Woo, Fran Manushkin, comes a series about Katie's pal Pedro. Join Pedro and his friends as he enjoys adventures at school, on the soccer field, and at home with his sometimes pesky, younger brother Paco!

A collection of adventures in which seven-year-old Pedro is frightened by monsters in his dreams, experiences the frustrations of a broken arm, locates his lost brother in an amusement park, and deals with both bullying and a bad smell in his classroom. Includes joke pages.

When Pedro gets separated from his class during a field trip to the aquarium, he manages to find them by taking a cue from a shark he saw swimming in circles. Includes a glossary, text-related questions and writing prompts, jokes, and a website for further resources.

Miss Winkle separates the class into teams and instructs them to build towers out of paper cups, and the group who builds the tallest tower wins--but they have very little success until Pedro has an idea about how it can be done.
