I've noticed in-game that the Majin starting area is called Bee Village. Yet in quest text it refers to it as Bay Village, which admittedly doesn't make much sense.

It translates to "Abbe".

What are we calling this village? We need to fix this.

Well it would make sense for Bee which I changed it to in my own translation. This is because Majin Buu named the dog Bee.
I even changed all Yahhoy to Yahhoi

You have your own translation?

Yeah I work on one myself when I get bored grinding. I add most of the stuff I translate to the tool on the forum.

Although, in the music files, the file for that town's theme is called "bgm_beh_village.ogg".

But Bee sounds better.

I agree. I like Bee better myself.
