[It's called Sweet Bat Pony Curse. But it is called SBPC for short. It originated from a science experiment gone wrong. It is super aggressive and cannibalistic. It can be transferred through saliva. It is more common for other bat ponies to get it. The symptoms are: losing weight, paranoid about bugs crawling inside their skin, losing pigment in their hair, losing the ability to fly or use magic, intense head aches, fevers, lose of vision, weak legs, and a weak immune system.]
