In my Marketplace Money interview, I mentioned a humanoid shell creature my grandmother gave me as a child. I just remembered I have a picture of it, which I took before I threw it away just two years ago. Paaaaaaack rat!
Actually, according to Wikipedia, if I was a true pack rat, I would have incorporated the shell into my nest, or at least traded it instead of getting rid of it: “A peculiar characteristic is that if they find something they want, they will drop what they are currently carrying, for example a piece of cactus, and ‘trade’ it for the new item.”
Mmmm. Nest cactus.
