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.

"With all new Dog Man comic" stated on front cover.
