What if someone tried to raise a fluffy as a human for a science experiment, a la (the very sad and unethical) experiments done with Nim the chimp?
I’ve seen a comic where a mourning mother tried to replace her dead son with a fluffy by raising him as human (good comic too), but not any more science-based abuse like this.
I did some thing sort of similar to this. Instead of the fluffy being raised slowly he was instead bombarded quickly with a bunch of human information which made him intelligent.
