-Klowns display something known as Polyphenism. Basically, what this means is that Klowns can vary wildly among members of the Klown species, each with different adaptations and hunting strategies.
-The Klowns are basically hemovores, AKA exclusively feed on blood. They CAN eat human food, but too much makes them sick.
-The reason why the Klown's nose is their weak spot is that it's like the brain stem in humans. It controls all their bodily functions. If that is destroyed, they can't live long without medical assistance.
-the Reason why Klowns assimilate other species into their ranks is to learn how best to hunt them. A former member of that species will know exactly how to trick and fool a member of their own species, and plus it's a great way to learn that species language!
-Klowns will only attack young children if they are basically starving or there is no other viable target nearby. This is the reason why Jumbo went after the young girl in the diner, he didn't want to cause a fuss by attacking any of the adults in the diner and bring too much unwanted attention to himself.
-Klowns are very eager to learn about other cultures, as they love to entertain when they are not hungry.
-Mimeism is the Klown version of Albinism. These klowns have no color in their 'makeup' or hair, making them pitch black. Jackie is a notable sufferer of this.
-Female Klowns often don't go on hunts because they are the ones who stay behind to protect the Big Top from attack.
