The most fearsome beast ever known to man, immortalized in my pumpkin carving from this past Halloween.
From the "International Guide to Fearsome Creatures, Volume 38":
"The hippigerobradactyl is truly a magnificent killing machine. With the body of a hippopotamus, the head of a tiger, a king cobra for a tail, and the wings of a pterodactyl, it is well-suited for terrorizing and slaughtering indiscriminately from any terrain or even from the sky. Few are the men and women that have stumbled upon the hippigerobradactyl in the wild and lived to tell the tale. Even those are rendered psychologically impaired from the harrowing experience, and piecing together their stories into coherent descriptions of this beast is a project of massive proportion undertaken only by the most highly trained counselors, psychologists, and biologists."
