Elevate kids' playtimes with the Lego City Off-Road 4 x 4 Mountain Truck playset for boys and girls. Kids can use the winch to traverse steep inclines, flip the vehicle snorkel to pop up the hood and access tools and equipment in the roof storage boxes. The Lego Builder app takes kids on an intuitive building adventure with tools that let them zoom in, rotate models in 3D and track their progress.
