The rolling wheels underneath the wings allow the airplane to move smoothly on different surfaces, providing a dynamic element to the play experience. Toddlers can push or roll the airplane along, encouraging their motor skills and coordination. The three holes on the toy serve multiple purposes, acting as imaginary windows and finger holes for little fingers. Children can use their imagination to pretend they are peering out of the windows or use their fine motor skills to explore the toy by placing their fingers through the holes. 2+ years old Measurements:6in x 6in x 3in
