In the darkest depths of the ocean, beyond the realm of man's understanding, lies Great Cthulhu. The last of the Great Old Ones, who sleeps in the sunken city of R'lyeh, awaiting the time when the stars will be right and he will break out of his tomb, free to feast upon the souls of man...
...But in the meantime, he is still trapped at the bottom of the ocean in his city looking for a way to pass the time. His solution? Start a phone-in talkshow in which people can phone him about anything, ranging from secrets of the old ones to farming advice. ''Calls for Cthulhu'' (a pun on ''The Call of Cthulhu'', the original Lovecraft story) sees the title character (portrayed by a handpuppet) answering questions from viewers on all sorts of topics and providing advice with varying degrees of helpfulness (in between boasts about his intentions to swallow the souls of his callers- and occasionally he'll swallow the soul of a particularly annoying caller over the phone).
Not to be confused with Literature/TheCallOfCthulhu, the original short story from which the character originated.
!This series provides examples of:
* EarlyInstallmentWeirdness: In the first two episodes, the visuals to the intro are not as clearly developed and the set is a lot more simplistic.
* EldritchAbomination: Cthulhu. Some of the bigger ones are referenced occasionally and Shub-Niggurath phoned in one episode.
* EldritchLocation: R'lyeh is built up as one, though we don't see much of the non-euclidean geometry.
* LovecraftLite: Ironically many of the cosmic horror components are still present, but it's hard to take the Cthulhu hand puppet seriously.
** Cthulhu also occasionally talks about having real estate problems and runs a "suicide hotline" as "community service" (though he has a tendency to abuse it).
* TheGhost: Tim, Cthulhu's assistant.
* MoodWhiplash: The intro always starts off with a dark and epic feel, creating a sense of terror and cosmic horror as we learn about the mysterious Cthulhu... before announcing that Cthulhu is answering phone calls from viewers.
** A running joke is for Cthulhu to respond to a caller (usually the first) by announcing that he will swallow their soul and delivering a speech about the inevitable horrors to come... then casually answering the viewer's question. The inverse is fairly common as well.
* TheUnpronouncable: Parodies the use of this when Cthulhu outright refuses to tell a caller how to pronounce his real name.
* TrademarkFavoriteFood: Cthulhu is constantly talking about swallowing souls. He even had a segment in which he tried to do a cooking show demonstrating different recipes.
