Some day, a young guest of the Warrick family, called Norky, got the Ewoks Wicket, Teebo, Princess Kneesaa and Latara into trouble. So, the four decided to take an action against Norky: they duped him into following a "treasure" map to the valley by way of Latara's hang glider.
But the four young Ewoks went immediately to the Vacant Valley, in order to save Norky, when Logray told them that it was the centurial time of the natural sucking phenomenon in the valley.
