The beasts that show up on the bottom of this page were inspired by bad taxidermy. Their creator–if you can call him that–was mostly concerned with their inner workings, and he was a little fuzzy on how to put them back together once he was done spelunking around inside of them.
I’m not sure they can close their mouths or blink. Is it possible to have animals who can’t blink? This is kind of nightmare fuel-y to think about, but would their eyes dry out and stop working after a while? (Also, I’m not sure these guys’ eyes are functional.)
