My partner's favorite transformation is plushification. A stark soft contrast to my usual hard statue transformation love <^^ alas, with the tug of their beard they'll poof and turn to fabric, becoming a cute inanimate squirrel plush, which I can pick up and snuggle, boop its squeaking nose, and enjoy keeping them that way for as long as I'd like.
A feature I made for my partner Squiz in Neos VR.
