Roptor

Clever girls they are. They tend to hide behind bushes that only exist in their imagination, therefore they look kind of stupid should you encounter one of them.

But beware - their acceleration is something to be feared. Especially if they picked up a jomper pack. Your only hope is to get on a big hill and start worming away. Except if you are a child, in which case they start hitting imaginary kitchens.
