The LEGO DUPLO Batman Batcave (10919) blends imaginative play with developmental skills, inviting young superheroes to join Batman and Robin on adventures. The set includes a Batcave with a jail that has an opening gate, plus a Batmobile toy for action on the go. Kids can use their fine motor and problem-solving skills to catch The Joker—who comes with a slime shooter—and return him to jail, though the high-speed Batmobile ensures plenty of surprises. Designed for small hands, the pieces are easy to grip and place, making this a great introductory set for children ages 2 and up. The Batcave measures over 5 inches high, 8 inches wide, and 3 inches deep, while the Batmobile is more than 4 inches long. It also connects easily with other LEGO DUPLO sets for expanded play.
