Neanderthalensis Marconis, more commonly known as, Hee Hoo, is a wild beast, that is inside all of us. The first case of Hee Hoo was discovered in YouTube sensation, Mark Fishbach. (Markiplier) Mark was pushed off the edge just to much, and Mark snapped. “I’ve never seen anybody move like that” said Ethan Nestor (CrankGamePlays) who witness this horrific transformation. “Until Hee Hoo is captured, scientist can only theorize as to the cause of this rapid de-evolution. Some speculate it was stress, a pressure from an outside source over a period of many months.” Scientist worry that this “break” may lurk within us all, waiting to reveal itself. The was a documentary called, “Hunting Hee Hoo” but as of November 13th, 2020 the documentary has since been deleted, due to the final wishes of our overlords, Unus and Annus, never to be seen again. We can only hope, that this will never happen again, to anyone.
