Hi I am selling an Original Brio Adventure Tunnel with Sounds. It will come with 2AA batteries to make the sounds work. It does have the little yellow bridge missing on top and does have general marks from being used otherwise still in good condition. You have to  Press the little yellow button on top of the tunnel to hear various sounds. The track is wooden and the tunnel is plastic. It has the Brio logo on the base and on one side of the tunnel.
