Giant multicolor train keeps a preschooler busy and active for hours. When assembled, and connected, the all-wooden choo-choo measures 20 inches long and is approximately six inches tall with fully stacked blocks. Each car has wheels with rubber grips for a smoother ride. Colorful blocks feature pieces to build a locomotive and cargo, and three animals: a rabbit, a chicken and a duck, all with spring necks, that can ride from room to room with your little engineer.
