Etymology[]
"Grapenyan M" is a combination of "Grapenyan" and "Mega", due to him being a Mega (M) Yo-kai.
Trivia[]
In the internal text data for Wibble Wobble, he is referred to in Japanese as Budounyan M (ぶどうにゃんえむ).
These were left in the data because there are separate unused text fields for names written exclusively in hiragana; because of this, it's not known if the proper form of this name would be written with kanji characters (like ブドウニャン M) or not.
