The LEGO DUPLO Town Alphabet Truck (10421) set provides a fun and engaging way for preschool kids to learn letters, colors, and improve their language and motor skills. Toddlers can connect the trailer to the toy truck, helping the 2 LEGO DUPLO figures to load and unload the bricks which aids in letter recognition. The set comes with a LEGO DUPLO ABC book toy element and a stereo element to inspire ABC sing-alongs for parents and toddlers. With 36 pieces in the set, toddlers can recreate scenarios, develop stories and take their toy truck cab off for exciting adventures. The LEGO DUPLO set encourages open-ended play, self-expression, and learning, making it a perfect gift for children ages 2 and up who are beginning to recognize letters and love vehicle toys. Safety is guaranteed as all the bricks and pieces have been rigorously tested to meet demanding child safety standards.
