David explains how gnomes build their houses. The entrance of the house is under a tree, with an underground tunnel leading to another tree. Many other gnomes and animals help build the houses. David and Lisa get a message from a rabbit about a deer with a broken leg. They both go to help the deer, who had fallen on a sharp rock, and part of it was embedded in her leg. David removes the piece of rock and puts a splint made of branches on her leg. Later that night, David also has to remove pine cones from the throat of another deer.
