Chubi Boom is a large indoor play center. Kids work through a colorful maze with slides and hidden games, a ninja obstacle course with monkey bars and ropes, trampoline tracks, and a pool of boats they can steer.

Under-3s get a separate toddler zone with a low treehouse, ride-on toys and sensory panels. A token arcade, birthday rooms and an on-site restaurant round it out.
