Maybe in this fanfiction, Cthulhu's influence starts seeping into the dreams of demigods. Percy Jackson starts having these really strange and terrifying dreams that he can't explain. He then discovers that other demigods are having similar experiences. Together, they set out to find the source of these dreams and end up in a battle against the minions of Cthulhu. Percy has to use his skills with water and his demigod strength to fight off these otherworldly creatures while also trying to figure out how to stop Cthulhu from invading their minds completely.
In a fanfiction, perhaps the gods in the Percy Jackson universe are aware of Cthulhu as an ancient and powerful being from another realm. They send Percy on a quest to learn more about Cthulhu's weaknesses in case he ever wakes up fully. Percy teams up with some of his demigod friends and they encounter all sorts of Lovecraftian horrors along the way. They soon realize that Cthulhu's power is far greater than anything they've ever faced and they have to rely on their wits and some newfound magic to survive.
