Some of them represent places in the country. America's represents Nantucket. Austria's represents Mariazell. Norway's represents The Fjords. Italy's and Romano's curls represent their E-zones. South Korea's represents his "Korean Spirit" which is why it is often shown with a smiley face in it. xD Some of their curls I believe can also represent their failures and victories.

And when he was a Чиби his curl was a lot curlier because he would always get beat up by Hungary. And with the Italy brothers their curls and really big and curly because they've Остаться в живых a lot of battles. The other country's curls I'm not sure.Больше года
