Nintendo of Europe has launched an official Twitter account for Isabelle (under @AC_Isabelle), one of the main 
characters in Animal Crossing: New Leaf.
In the game, Isabelle awaits the arrival of the new mayor in town. Nintendo figured that it would be fun to have that character tweet about her experiences in the game.
Hello! I'm Isabelle. I'll be tweeting about the pleasant life in Animal Crossing: New Leaf for anyone thinking of moving into town!

I'm eagerly awaiting the arrival of the town's new mayor. Our former one, Tortimer, has moved to a tropical island! ow.ly/i/1TVGo
