@o76923 @mym Oh cool, word of god time! :neobot_floof:

All Neobots come with a conformable Averex skin to allow for maximum emotional range and protection from falling anvils. The "floof" state is the result of the emotional display subsystem becoming overloaded, causing actuators to fire at random, giving the bot its spiky appearance.

This is completely distinct from neobread_floof, where the bread simply grows fur somehow. :neobread_floof:
(Yeah you can blame me for that one too.)

(Since the internet is being stingy with a relevant link, "Averex" is the infinitely stretchy material cartoon characters are made of, it's named for Tex Avery.)
