Once upon a time there was a being, and it met a girl named Felicity Brewer.
The Being needed Felicity, so she chose him for her own. And her love made The Being grow so big, that the Brewers had to leave their home. The Being’s the best friend anyone could know. “He’s the greatest thing ever. I really think so. The Being’s so loyal, he’s there when you call. I love The Being who sought me out!” So they packed up the family car and the Brewers left the city. They moved to Birdwell Island and found many new friends waiting there to greet The Being and Felicity. “The Being’s so much fun, he’s a friend to us all.
I love The Being who sought us out!”
So, that’s obviously a story pitch for a feeder from another dimension who met a girl, confused her with a perception filter and began eating her emotions, then as it gained power convinced her to move to a remote island where the whole village, drawn by its power, came out to meet them and were assimilated as prey.
Or it’s the theme song to Clifford, the Big Red Dog, with names changed to protect the innocent. Your call.
