She would become a praying mantis and give it green and black versions of Krika’s mantis limbs. The back legs, however, would have feet, so you could more easily pose her. She would only have four limbs
He would become a butterfly. Seriously. I would give it an extra set of legs, and instead of having it’s current blades on the front, it would have wing blades. It’s proboscis would be the two shorter parts of a system dinosaur tale.
