Nonno is usually a cute and meek hamster, and sometimes she likes to be an airhead. She is sometimes very prideful and is often mean. However, she can also be very kind and gentle to the Mini Hams.
According to the "Minihamuzu Tomodachi Book":
- Her favorite foods are apples, pineapples, melons, watermelons, strawberries, and sunflower seeds.
- She loves going to amusement parks to play.
- She is the only hamster in the series that has visible fangs. This is due to Nozomi Tsuji having done a yaeba procedure to her teeth (which she undid later in life).
