Zim-human

It was chemistry class and the teacher had said that groups should be made. You thought your friend Dib was going to be a group with you until someone else sat next to you, it was Zim, the new guy and kind of weird in your opinion.
"Hello, I'm Zim!" He introduced himself with a big smile and a somewhat squeaky voice, you looked at his green eyes and then you saw the hand that he was extending to you in greeting.
