That's the point of the Tsuchinoko: it's a cryptid that's basically unremarkable, aside from its slightly deformed appearance. In real life, it could have been a snake digesting large prey, a short-legged lizard, or a reptile with achondroplasia.

That was the joke with Ash in the anime: a Pokémon that was unremarkable, but he couldn't catch it.
