"BECAUSE I WANT TO PARTY WITH THE CUTE BOOOOYS!!!!"
Estonia is a Baltic country who wishes to be part of the Nordic countries. She tries to invite herself to their parties but they never accept her. She has a good relationship with Finland and knows what vodka he likes but he still does not view her as a Nordic Country.
Despite having God's favor she is unlucky as she had two gifts (special red and white "winner flags") from him stolen from her (once by Denmark, and once by fellow Baltic Latvia) in comic, No Flag for You. Despite normally wearing her horizontal tri-colored flag, she sometimes tries to infiltrate the Nordics using a blue flag with a white cross similar to the ones they wear.
One reason that she is insistent on joining the Nordics is that she thinks the male representations of the countries are attractive. She is the most succesful among Baltic sisters (she can afford having a hat), what makes her more confident about being Nordic.
