The first of these mentlegen was featured in my main gallery, and is kind of just this ancient, braindead old thing that used to be used for nurturing developing human fetuses within those funky bulge things all over its body.
'Course, its original outer shell fell off a few hundred years ago, give or take a few, which is why it's a big mess of wires.
Now it kinda just wanders around, "caring" after various random wildlife, thanks to what remains of its decayed programming.
As for the other one... uh, it likes Harry Potter.
