The Tsuchinoko (translated to English as "child of hammer" or "child of dirt") is the name of a small, snake-like creature in Japanese legend, known for having a disproportionately pudgy body ending in a slender, pointed tail. They are typically jet-black or dusty-brown and can be as long as 12 to 31 inches. Their behavior is noted to be strange, defying behavior seen in similar animals and even defying certain laws of physics. They can bite the end of their tail to form a wheel to travel faster
