She is a small, determined and fiercely independent Mymble. When she wants something done, she does it straight away. She is very aggressive and totally disrespectful, but can be a good friend. She has a brash personality. She is Snufkin's half-sister. A comment in Moominpappa at Sea about people who have been adopted may be read as implying that little My was adopted into the Moomin family.[2]
