Choo-choo! All aboard for a fun-filled adventure with the Melissa & Doug Design Your Own Railroad Floor Puzzle. This engaging set invites kids to piece together 48 sturdy cardboard jigsaw puzzle pieces, each featuring built-in tracks to design their own railroads. The grooves in the pieces form twisting and turning train tracks, creating a fun path for the two included wind-up toy trains – a traditional locomotive and a speed train. Children can wind them up and watch as they zoom along their custom track designs. With up to 20 feet of track and four add-on scenery pieces that attach for pretend play, this toy encourages creativity and problem-solving through thrilling sensory play.
