<highly random>Hmmm... I wonder if it's possible to use genetic modification to create lemmings(as in green haired ones) in real life? That's a thought.<highly random>
I just recently discovered that apparently Lemmings in the games don't have mouths!
So that sorta rules out any real-life animals that would look like Lemmings. Sure, they can be done, but without a mouth it would be tricky for them to eat anything, you know. And if they can't eat, they'd be long dead before they grew to adult size.
In any case, breeding an animal that would naturally starve to death is something too cruel for me to contemplate......
