Scholastic has launched the new “The Adventures of Captain Underpants” app for iPad in the U.S. in conjunction with the release of the 10th book in the series, Captain Underpants and the Revolting Revenge of the Radioactive Robo-Boxers.

The app gives fans of the 15-year-old series a change to interact with their favorite characters, with a digital version of the series’ first book, The Adventures of Captain Underpants, in color for the first time, as well as interactive games and activities. Players also can create their own avatar and choose a silly Captain Underpants name.

“The Adventures of Captain Underpants” is available now in the Apple App Store.
