[Dr. Sivana]

Don’t forget Sigmund & the Sea Monsters. Sid & Marty Kroft put out some fun shows for kids during that era.

If I recall, they presented some ideas to McDonald's Inc., and had to sue McDonald's (and won) when the McDonald land characters came out (Grimace, Captain Hook, Mayor McCheese, Hamburglar, etc.)

Another bit of trivia regarding the show I had not heard.
