Bring dynamic, balancing fun to play with the educational Swing and Fold Tree (10440). This brightly colored building set for ages 18 months and up will provide hours of learning and fun for little builders in a cute treehouse with owls. This building set for young children is designed to help develop patience and problem-solving skills as they figure out ways to put the pieces together to make the tree balanced. Little animal lovers can add more bricks to secure the tree or simply explore the treehouse with LEGO® DUPLO® owl figures. Adults can use the day and night blocks to show children that these birds are active at night but sleep in their eggs during the day. Young children can practice their fine motor skills by opening the touch eggs and their color sorting skills by matching the owls to the eggs. This nature-themed toy can be rebuilt in many different ways, encouraging creativity and perseverance.
