Brio World Smart Action Tunnel 33935

The smart action tunnel pack is just one of the tunnels that brings action to your smart tech train from brio.

when the train passes through the tunnel, it makes the engine sound and move according to the brio tunnel icon: the turtle causes the engine to make chuffing and braking sounds as it slows down

the rabbit speeds it up again. Brio smart toys are preferably used with the brio smart train to enable sounds and movements.
