The LEGO® DUPLO® Truck & Tracked Excavator (10931) is the perfect building set for toddlers ages 2 and up who love to explore open-ended play. With 2 construction-worker figures, a push-along truck with a tip function and an excavator with a rotating digger, kids have everything they need to carry out construction-site tasks and develop their fine motor skills. The set comes with toy boulders that can be scooped up into the truck, but watch out, they can split open! The building site set is part of the LEGO DUPLO Construction playsets, which are designed to stimulate and satisfy the early developmental needs of preschoolers. The truck and excavator are the perfect size for little hands to pick up and place, measuring over 4” (11cm) high, 5” (14cm) long and 2” (7cm) wide and over 4” (12cm) high, 7” (18cm) long and 2” (7cm) wide respectively. With 20 pieces included in the set, parents and caregivers can watch their little builders develop their fine motor skills and problem-solving abilities while joining in the imaginative construction-site fun.
