Lego My World Modern Tree House (21174) 2021909 pieces is a large multifunctional toy set, which is very exquisite and can bring lasting fun to my world players and children who love creative splicing. In the reusable My World Tree House, children can assemble four completely different rooms: kitchen, library, study and bedroom, plus some realistic accessories of my world, from furniture and bedding to tools and TNT explosives. This costume encourages children to combine and configure repeatedly and explore imaginative ways of playing and displaying. These rooms don't even have to be spliced into trees. This suit is very suitable for imaginative children who are not satisfied with the traditional toy house.
