About Mel Blanc on the show, and the FRIENDLY PHYSICIAN, season 2, episode 29, the only time that they're off the island
Mel Blanc did a couple of voices on the show, a Season one parrot, and in season two, THE FRIEDLY PHSYICIAN,the dog and cat sounds, even the sputtering boat in the tag!
Speaking of THE FRIENDLY PHYSICIAN's tag closure:
It';s been noted, but in the tag, when they're finally back from the haunted castle, you can see RIGHT away a ship or something..it's the Studio City...:) ON THE ISLAND!
