The LEGO DUPLO construction and play set "Big Construction Site with Light and Sound" (10933) offers numerous vehicles, activities, and figures that inspire toddlers to engage in role play and promote their development. A large toy construction site full of play opportunities. There is a lot for little builders to discover on the busy construction site. The possible activities can easily fill an entire day. There is a large bulldozer, a mini bulldozer, a small wheel loader, a dump truck, and a crane for toddlers and parents to deliver building materials together, build a tower, and clear debris from the road. And at lunchtime, there's a snack at the hot dog stand on the construction site! A versatile set full of features. Five figures in modern outfits – a painter, a crane operator, two construction workers, and a hot dog vendor – along with plenty of cool features, such as light and sound bricks and the pushandgo pullback motor on the bulldozer, engage and inspire young children. The set can be combined with other LEGO DUPLO construction and play sets to provide even more developmentally beneficial play experiences.
