Did you ever watch the short-lived, 1970s Saturday-morning TV series Sigmund and the Sea Monsters?
It ran for only two seasons, but I think my sister and I watched every one of its 29 episodes. I don't remember much about the story line other it centered around a red-headed boy who had befriended a bunch of people dressed up like sea monsters. But the one thing I do recall from the show was a "Shell-ephone. " And whenever it rang, the sea monster answered it with a "Shell-o!"
