BRIO WORLD WOODEN TOY SMART ACTION TUNNEL PACK (#33935)

Smart Tunnels add extra action to BRIO's Smart Engine. When the train passes through the tunnel, the engine reacts and generates sound effects according to the BRIO symbol on the tunnel: the turtle produces characteristic "chaf-chou" sounds as well as brake sounds as the engine slows down. The rabbit helps speed up again. The accessories of the Smart Tech series are combined with the Smart Tech machine, which is essential for Smart functions.
