The Tsuchinoko literally translating to “hammer’s spawn,” is a legendary snake-like cryptid from Japan. The name tsuchinoko is prevalent in Western Japan, including Kansai and Shikoku; the creature is known as bachi hebi in Northeastern Japan.
Tsuchinoko are described as being between 30 and 80 centimetres in length, similar in appearance to a snake, but with a central girth that is much wider than its head or tail, and as having fangs and venom similar to that of a viper. Some accounts also describe the tsuchinoko as being able to jump up to a meter in distance.
According to legend, some tsuchinoko have the ability to speak and a propensity for lying, and they are also said to have a taste for alcohol. Legend records that it will sometimes swallow its own tail so that it can roll like a hoop, similarly to the mythical hoop snake.
The Tsuchinoko makes an appearance in the video game Metal Gear Solid 3: Snake Eater and closely resembles the pokemon Dunsparce. (Source: http://en.wikipedia.org/wiki/Tsuchinoko )
