Sigmund and the Sea Monsters

Well, I watched this show religiously, but at such a young age that as an adult I was unsure of what it was. I was only about three of four when it was on. I used to watch it and then Land of the Lost right afterwards. I did know that I loved the show and that it was about seamonsters but I always thought it was called Simon the Seamonster. I asked around on nostalgic tv show sites but no one seemed to know what I was talking about. Now that i have found the name of the show, I hope I can find copies of it to see. I do recall that it always had the parents I think coming up out of the sea and I remember a mom coming down a stairway to the beach area. That is all I can remember though, but it leaves a happy memory.
