Bring the thrill of a real construction zone to the playroom with the CAT Dig N’ Build Concrete Playset. Kids pour the 12-ounce compound into the tray, pack it into the molds, then raise their freshly “cast” blocks with the working crane or haul them away in the pair of Little Machines vehicles. The gritty sand-and-clay mix feels like wet cement yet wipes up dry, giving young builders sensory fun without mess. The 11-piece kit (model 83416) measures a shelf-friendly 9.8 × 2.4 × 8.3 inches and is durable enough for both carpet construction and sandbox shifts. Like full-size Cat machines, every part is built to last, and the set is safety-rated for children 36 months and up
