I'm confused...

I wiki said if you speak to Isabelle twice on New Years Eve, she gives you a tweeter. When I did that she just gave me sparkling cider, and if I talked to her several times she wouldn't give me the tweeter. :c And I drank all the cider on mistake, I was planning to save it. xD How am I supposed to get the tweeter?

Is your language set to french??

I got the cider too. I do have a tweeter though, I got it from streetpassing a handful of people at my school.

Tweeter is available in the UK and France.
Since you live in America, it's the sparkling cider.
