Oh please, you accuse Plana of being dirty claiming she has orgasms when she multiplies? You have the dirty mind, sir. Furthermore, Ika is FAR more sexual, she has the dozen or so tentacles...you KNOW what that means in Japan.
Plus, Ika is super-stupid, while Plana is actually like a genius (she can split into several different units, learn in each, then re-integrate and have the knowledge/experience of all the parts).
You just got served, son.
