Sorry I'm a bit technically challenged with the photo's but to give you some ideas I have some wooden bridge/tunnels , toilet rolls stuffed with hay, a toy tub turned upside down with the handles cut off and a door cut out, pine cones, apple branches, a metal bowl (they like to bang this against the slate tiles in the early hours) a plastic tunnel, a hanging basket with hay in and I put in any carboard boxes we end up with. Hope this helps!
