This nightmarish ghoul can enter the human through any entry point, but where they end up is particularly horrifying. They are known to travel through your body and finally settle in your eyes. NOPE.
While it is a rarity, earwigs have been known from times to time to come hang out in your ear canal just to freak you out.
You better hope you don’t encounter this pervert. This disgusting fish is attracted to ammonia, which humans release in urine, so the Candiru has been known to swim up flowing urine and infect the genitals.
