Send an animal to do some scouting

Taming: 37

Even if you have all the tools you need to get inside the mountain, you decide to use a rat as a scout. After showing him some tricks, the small rodent sinks into the tunnel. A few seconds later, the animal returns. Since it is unharmed, you infer that you should not meet anything too evil along the way.
