Snidjer was the leader of the Flitchaye, a tribe of runty weasels who lived in Mossflower Woods. He and his followers attacked Mariel and her companions and knocking them out using toxic herbal smoke. Snidjer briefly took possession of the Sword of Martin that Dandin was carrying and threatened the captured travelers with it. They were rescued by Stonehead McGurney, who walloped Snidjer before temporarily imprisoning the Flitchaye in their underground holes by laying a tree branch over the top.
Snidjer is not mentioned after this, though it is presumed that he and his followers killed Fishgill and his searats when Oak Tom tricked them into the Flitchaye territory.
