Not sure if Modular Fluffy Project by:Foxhoarder is relevant to your experiments, but it’s definitely worth mentioning here. Crowdsourcing and sharing resources ought to be the future of fluffy games in general.
Also, someone once tried making a fluffy AI based on an emotion circumplex model and letting the fluffies neural connections develop from scratch. For genuine stupidity, at one point it actually had a glitch where the fluffy went to the food bowl but never ate, because somehow it had learned that the act of going to the food bowl was what sated its hunger, not the eating.
