brio BRIO World Adventure Tunnel

See what you discover when you pass through the 33481 Adventure Tunnel. Shaped and coloured like a mountain railway tunnel, this sturdy plastic and wooden toy is finished with a realistic stone-effect surface and colourful flowers. It has four "real world" sound effects that are magically triggered when a train passes through it or by a simple push of the button on top of the mountain. Open at both ends under brick-effect archways, the tunnel interlocks easily with other BRIO World toys via the wooden track passing through it. The tunnel also features a flip-up bridge across its top for roleplay fun with BRIO figures.About BRIO World: BRIO World is our open-ended play system that grows with your child.
