I was reading Japanese article of wikipedia article of ツチノコ today and I thought it might be interesting to see how it is explained in English article.
So, I looked for the English article for Tsuchinoko.
It started innocently:
The Tsuchinoko (ツチノコ or 槌の子?) literally translating to "hammer's spawn," is a legendary snake-like cryptid from Japan.
Although I think it's "snake" rather than "snake-like", but it looks okay.
According to legend, some tsuchinoko have the ability to speak and a propensity for lying, and is also said to have a taste for alcohol.
I've never heard of this funny story. "ability to speak"?, "propensity for lying"? In what legend?
As usual, there is no citation for this.
In old history book such as Kojiki and Nihon Shoki, there is a god modeled from tsuchinoko. Sure. Gods and Spirits may speak. But since everything(animals, plants, mountains, rivers, rocks and literally everything) has corresponding god in Japanese traditional religion, It's not a special case for the Tsuchinoko.
Though it is said Tsuchinoko likes alcohols.
The later sentence:
Legend records that it will sometimes swallow its own tail so that it can roll like a hoop, similarly to the mythical hoop snake.
It looks like some people said this.
