The Snorks check out a construction site where Junior builds his empire. Occy digs up an old treasure map. Galleo tells the Snorks that the map was left by ancient Snorks. Junior steals the map and gives the Snorks a fake map to follow. They encounter a whole lot of dangers along the way while Junior thinks that the treasure is buried right in his own front yard. Galeo finds out that the treasure map is actually a warning about molten lava, an unfortunate proposition for Junior and his family.
