Synopsis:
Danny and his father visit an underground museum where a wooly mammoth is frozen in ice. After they leave the museum and returning to the forest above, a forest ranger spots a forest fire. Danny and his father join the efforts to put out the fire. Rex protects Danny when he gets into trouble. The fire releases the mammoth by melting the ice, so Rex leads it off a cliff. When the fire is extinguished, the source of the fire is discovered to be an ordinary match left behind by a careless camper.
