Surely one of the lamest episodes here, how is it that an extended steam session changes Scooby and Shaggy into babies? And when they change back near the end, Shaggy's clothes magically reappear after wearing little more than a diaper. It would have been more amusing to see him still in the diaper upon getting back to his normal age.
This episode was parodied in Johnny Bravo. The episode in question was "Look Who's Drooling". Carl takes on the role Scrappy-Doo had in this episode.
