1973-Sigmund and the Sea Monsters

Welcome to the bizarre world of (drug-induced?) Sid and Marty Krofft Saturday morning television.
Brothers Johnny and Scott meet Sigmund, outcast child sea monster that becomes their pet.
Episodes depicted their attempts to hide Sigmund and protect him from the devious efforts of his sea monster family. That weird kid from Family Affair played Johnny.
Season two got even more bizarre as Rip Taylor joined the cast as a magical 'Sea Genie' named Sheldon. Scary.
Twenty-nine episodes were produced.
