- Why Brain Moles are not in zoos.
Brain Moles have been in D&D for a long, long time, and like most pure psionic monsters, the main question players ask when first coming across them is "What the actual f*ck?". Tiny, velvety things, these pests are vicious cogitovores (I made that up), and will seriously ruin your day if they are allowed to get a "grip" (either psychically or physically).
So, here you. Hide your brain!
