The saying 'as quiet as a mouse' does NOT apply to Ruby Loud Mouse. Ruby finds it super tricky to stay SILENT in movies, to WHISPER in the library, or to keep QUIET on the school trip to the marae. In fact, Ruby is SO LOUD everyone is always telling her to 'sssshhhh!'. But when her village is under ATTACK from a ruru, Ruby learns that sometimes being LOUD is the best thing to be.
