Wait, I thought they were called Bub and Bob? whats with Bubblun and Bobblun? why are they wearing shoes and gloves like they're Sega mascots (they're not wearing that in the smash bros like cutscene they showed)? I don't really know what to make of this game
Those were always the name in Japan and the localizations would just change them to whatever and/or pretend they're different characters.
That look with the goggles started showing up in the smartphone era IIRC and I guess they're sticking with it.
