Stan Lee himself has officially announced the next picture book from Stan Lee's Kids Universe, the children's imprint founded in 2011 by POW! Entertainment and 1821 Media: Katya Bowser's Dex T-Rex, The Mischievous Little Dinosaur will debut July 23 at Comic-Con International. Watch Lee's video below.

The book, about a loveable young dinosaur who plays too rough, until he learns an important lesson about playing nice, is the latest addition to the imprint's lineup, which already includes Monsters vs. Kittens, Once Upon a Time There Was a Pig and Reggie the Veggie.

"My hope is that parents will appreciate the messages in the book while children will be so drawn to the colorful pages and fun storyline that they won't even realize that they are learning and building their imaginations as they follow along with Dex on his adventures," Lee said in a statement.
