S1·E4 Someday My Prints Will Come

While exploring an ancient storeroom of the Great Gummis, Tummi discovers a mechanical decoy used to make dragon footprints, but accidentally starts the ignition on the machine and begins bouncing all across the land. The footprints attract a real dragon who proves to be different from the stereotype of large dragons. The knights of Dunwyn also see the machine and think it is a real dragon.
