Yikes! I guess the naked alien scammers were right when they referred to him as being a rat-monkey (I think)The whiskers and dog-like eyes certainly help it feel more real and mammal-like (that's how we all imagine it anyway, though being an alien it could be anything) I'm also interested in the dark matter too (In Fry's words, I have never been so excited to see poop, well, maybe once) it sure looks like its dense, heavy and radioactive as it's represented in the show. I suppose it contains the collective total mass of an entire zoo's worth of animals he ate not much earlier
