You found Riddle Snake!
Many consider the mythical Greek creature Sphinx to be the ultimate riddler ever existed on Earth, but actually it is Riddle Snake. A distant cousin of the rattle snake, this highly intelligent animal knows countless riddles and has the ability to display them on its skin. Just like the Sphinx, it is also very ferocious, and kills anybody who can't answer its questions. It is said that Riddle Snake knows everything about anything in the universe, even what the meaning of life is.
