“Yes, it makes perfect sense! You go to bed early and wake early, don't you!”
Mitsy is a very polite girl living on the first floor of Flopside during the events of Super Paper Mario. She spends her time asking her grandmother how she came to live so long. She seems to be less naïve than her Flipside counterpart, Betsy.
