General Information
Brain Slugs are little parasitic slugs that attach to an intelligent beings (such as humans) head and control it. They are about as big as a fist, green, translucent and have two feelers and one enormous eye.

Behaviour
A brain slug controls every intelligent being to whose head it is attached. The victim will be likely to speak in a monotone voice and do everything to further the spreading of brain slugs throughout the universe. The recommended procedure of dealing with a brain slug victim is to act casual and switch to a garlic shampoo to avoid being controlled as well. Otherwise assimilation threatens. Ways of denying attachment include wearing a helmet.
