What a perfect "starter kit" to a childhood of LEGO DUPLO creativity! Let's begin with a rolling wagon base your child can build onto, along with a boy and his dog to play with. Two window elements to use in building, with numbered bricks to help with counting skills. Many extra pieces – 65 in all – fit nicely into the iconic LEGO box.
