For me personally, Nana the monkey reminds me of my grandmother.
I called my grandmother "po-po," which is "grandma" in Chinese, and Nana's catchphrase is "po po." (It's also funny, because Nana's name means "grandmother" as well.)
In Happy Home Designer, Nana requested I make her a house with a "serene park" theme. Made me tear up a bit, because my po-po died 4 years ago, so I made Nana a simple, beautiful house and I left my po-po a short message. (If you'd like to see it, the code is 0900-5734-936.)
Are there any villagers that you remind you of people?
