George and Harold are best friends who enjoy making their own comic books.

Together they've created the greatest superhero in the history of their elementary school: Captain Underpants! His true identity is SO secret, even HE doesn't know who he is!

In celebration of the book's 25th (and a half!) anniversary, this special edition of The Adventures of Captain Underpants includes an all-new comic by Dav Pilkey, starring Dog Man! Tra-la laaaaa! It's can't-miss fun!
