Chug into learning with the Go Go Smartwheels Tractor and Trailer from Vtech! Detachable trailer includes a SmartPoint location that interacts with all Go Go Smartwheels Smartpoint vehicles triggering fun phrases, music and sound effects. Cute tractor interacts with SmartPoints locations on other Go Go Smartwheels play sets (each sold separately) and carries a bale of straw for even more role-play fun. Press the light-up button or push the tractor to activate 3 sing-along songs, 6 fun melodies and lots of tractor sound effects.
