To the Batcave! While reading a simple story about chasing a group of Super-Villains consisting of Joker, Two-Face, and Harley Quinn, fold this book out to explore four different vehicles inside and out-and meet Batman, Robin, Batgirl, Nightwing and more! Each page has a flap to lift for added seek-and-find fun, and the back sides of the pages feature a full spread of the Batcave with all of the characters you’ve met along this caravan!
