Yet another example of a distinct reindeer type is the ancestor reindeer, reindeer belonging to the 2-foot tall idols of particularly powerful and important ancestors of theirs that the Nenets keep in their chums. These idols are dressed in Nenets clothing and the family makes new sets of clothing for them each year. There are also a number of god idols. The ancestor idols are kept in the chum and the god idols are kept on a sacred sledge along with materials for making them new clothes. When moving camp, all these must be kept on the sacred sledge. No one must ever sit on this sledge. When a sacred sledge becomes old and breaks down it must be left at the nearest sacred site.
