"Rush will appear and begin to sniff the area. If he finds a hidden item, he will begin to dig and the item will appear. Many times he may just dig up some useless junk, but most of the time he will find a special item. If Rush Search finds a hidden room or passageway nearby, he will bark and go crazy. Search around the walls to find the hidden area. If he just stands still and yawns, there is nothing hidden in the vicinity."
