Yeah, I'd like to take a human soul too, and give it to my (proposed, I can think of another if you're not fond of the idea.) character, Monster Kid's big sis. Would it be cool if absorbing the soul gave her arms? Cuz uh... I would like her to have arms. 

Either that, or Alphys could build her some SWEET ROBO ARMS. I'd be cool with that too.
