Choo Choo, Choo Choo! It"s the Choo Choo Train Tunnel from Pacific Play Tents - full of fun! 6 windows per side make this train tunnel seem very realistic. Our conductor"s face is on the zippered front for added playfun. These tunnels promote the use of a child"s imagination while helping develop motor skills and muscle strength. These super fun tunnels teach kids cooperative interaction. So, climb aboard and ride on into the station. Tunnels fold down flat for easy storage.
