Now THOSE are some nicely designed alien beasties! Far too many alien creatures, in my opinion, are thinly-disguised versions of Earth animals - usually some kind of lizard or octopus - or technicolored humans with a few extra features. The Brain Bats, on the other hand, look convincingly alien - there's a hint of an octopus about them, and a bit of manta ray, and of course their heads look like brains, but the precise combination adds up to something really unnerving. Good stuff.
