I share my birthday with Cranston on September 23rd. He's quite adorable actually.
And the birthdays I could have shared with a villager in the month of September are Ankna(September 22nd! That's really close), Apple(September 24rd. Close as well), Whitney, Octavian, Kody, Marshal(._.), Mitzi, and Ed. And the ones I listed are all my faves. September is full of my villager faves...
I share mine with Tutu - I've never had her but she looks like a nice girl! I think the big bear character design is my least favourite but you should never judge a bear by its cover... or whatever that saying is.
I just looked it up and apparently I share on with Soleil (who I've never heard of before this moment but apparently her catchphrase is 'tarnation' so she's already cool in my book)
