Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 2: The Revenge of the Ridiculous Robo-Boogers: Color Edition (Captain Underp by Dav Pilkey

4.0

A nice conclusion to the arc started in the last book. I really like these for my son. They have inspired him to learn (and use) new words and shown him how fun it is to be engaged in a story. (I also appreciated all the Dad humor puns scattered through every book. I snorted at "the capes of wrath").
