She's a grumpy, serious, physically strong, hotheaded, short-fused, short and sarcastic anthropomorphic mouse. She speaks in gibberish formed by symbols and characters. Ma-san is the drummer of the little band, MilkCan, along with Katy Kat and Lammy. She has yellow fur, a stick of dynamite lodged into the top of her head. Its fuse lights in a comical way when she's REALLY mad. She basically doesn't wear anything BUT a red, strapless cocktail dress. She has big feet and big hands.
