And ニャーブル (Nyaburu) is just a name. Doesn't mean anything. A lot of the names they use in the anime and game, they start off with Nya-something. Example: Nyasuta, Nyami, Nyaito, etc.

"Nya" is the sound that Japanese people think cats make. Over here, we just think that cats say "meow". Meow would not be a direct translation, it's just a replacement to Nya so that it would make sense to westerners. Same reference, different culture.
