Black Nanda?

Before I wrote about the somewhat strangely named "White ’Black Thunder'". This week, our coop is selling "Black Nanda?" instead of "Black Sandaa" ("sandaa" being a transliteration of "thunder" into Japanese). "Nanda" means "what is this?" so it is a word play thingy: "What black thing is this?"

The answer seems to be that it is actually the same thing as normal "Black Thunder".
