Sigmund and the Sea Monsters, on Amazon
IMDb; TV Tango; Wikipedia

This webseries is a reimagining of the 1970s TV series of the same name, which I never saw. The pilot was released in June 2016, and the next six episodes in October 2017, but I first watched the season in June 2018.

There are two brothers named Johnny and Scotty, who always spend their summers visiting their aunt Maxine and her daughter, their cousin Robyn, in the seaside town of Dead Man's Cove. On this particular summer, the three kids meet a sea monster named Sigmund, and become friends with him. Sigmund lives in a cave with his mother and his two older brothers, Blurp and Slurp, none of whom like humans. Meanwhile, there's a guy named Barnabus (David Arquette) who has spent years trying to prove that sea monsters exist, and almost everyone in town thinks he's crazy (especially one guy named Zach, who loves to mock him). But Maxine wants to date Barnabus... which seems to make no sense, though eventually a bit of backstory is revealed that sort of explains it. Anyway, she doesn't believe in sea monsters, but she also doesn't think he's crazy. And they do sort of become a couple. And... most of the stories are about the wacky stuff that happens while Sigmund and the kids are just having fun, or whatever. Though eventually Barnabus comes to believe sea monsters aren't real, and decides to give up his obsession. There's a plot twist at the end of episode 7, though. And I don't know what else to say. It's just a really silly show, but I think it's pretty cute and fun. So I'm a bit disappointed to say that there's apparently not going to be a second season.
