Minnie Mouse usually makes cameos in the series, so a few things were known about her.
Minnie Mouse is obviously a mouse who wears a bride dress in SML videos. However, in cartoons she wears a red or pink dress with polka dots.
She is very attractive, and she seems to be loved by most people, (especially Tony), but Tony is so obnoxious that she occasionally avoided him.
Minnie Mouse is well-meaning, kind, outgoing, sweet, caring, and friendly.
