Tempting as it is to kill any and all of the... things listed, I don't think I'd actually want to eat any of them. On the one hand, I don't like mushrooms, and for the rest I just wouldn't want them to become a part of me. I'd rather try some mermaid, which, besides potentially being both fish and mammal, has the chance of making me immortal.
Oh, and if we eat all the smurfs, what would you use to fuel... whatever you fuel with them?
Ziox: Now with lapitithamine.
