Some cliche horror plot with an original backstory?
When I was 10 or so, I used to browse furby videos on the web and found people used to (and probably still do) circuit bend furbies either for experimental purposes or just to destroy them out of anger. Just a funny horror idea of the furby became sentient.
i do not own the slightly modified furby manual.
