Just had a random assed thought.
A Female Cell absorbs someone with her tail, but doesn't send them all the way through. Instead, they feel the "needle" get tighter around their feet and they're pushed into something else that forces them to curl up. On the outside, whoever is nearby gets to watch as the Fem Cell unbirths someone she was just trying to absorb. And thus, a new breed of Cell Junior is born. With the personality, power and temperament of the absorbed.
