thats why i slashed and said near silent. they make noises from time to time but rarely talk and when they do its a few words, same as mario who might scream or whatnot but doesnt really talk.
i could see a mario movie being a bit like a more action oriented minions, a story kind of like odyssey would work really well imo.
have toads, bowser, bowser jr maybe peach talk and have mario and luigi not talk
