One book is actually titled The Power of Lulu!. On its cover, the villainous, hairless guinea pig can be seen wearing an orange crystal around their neck and sporting a Doctor Strange-esque cape. Another set of toys allows kids to use Merton the turtle to battle Lulu's guinea pig henchmen.

League of Super-Pets is set to hit theaters on July 29, having been pushed back from its previous planned release date of May 20. The film features an all-star voice cast, including Dwayne "The Rock" Johnson as Krypto the Superdog (Superman's dog), Kevin Hart as Ace the Bat-Hound (Batman's dog), Vanessa Bayer as PB (Wonder Woman's pig), Natasha Lyonne as Merton (the Flash's turtle) and Diego Luna as Chip (Green Lantern's squirrel). Additionally, John Krasinski, Keanu Reeves and Marc Maron voice Superman, Batman and Lex Luthor, respectively.

In addition to Superman and Batman, a number of other DC heroes will also appear in the film, including Wonder Woman, Cyborg and Green Lantern (Jessica Cruz). It's also currently unknown who will voice characters like Pigasus and Lulu. On that note, Kate McKinnon, Thomas Middleditch, Ben Schwartz and Jameela Jamil have all been cast in undisclosed roles.

"Krypto the Super-Dog and Superman are inseparable best friends, sharing the same superpowers and fighting crime side by side in Metropolis," a synopsis for League of Super-Pets reads. "However, when the Man of Steel and the rest of the Justice League are kidnapped, Krypto must convince a ragtag group of animals to master their own newfound powers for a rescue mission."
