tsuchinoko
The Tsuchinoko meaning "hammerspawn", 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 centimeters 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.
Kirisame Marisa adopts the tsuchinoko found in Eastern and Little Nature Deity as a pet.
