FennoSwede was conceived as part of a desperate move on Sweden's part to prove he was straight, though in Sweden's defense, he was also drunk at the time. Sweden regrets the incident, but acknowledges FennoSwede as his son and spends enough time with him that he speaks Swedish by default. (Of course, he probably would anyway...no one exactly speaks Finnish at his home, except for the occasional swear word.)
FennoSwede looks very similar to Scania - who is, after all, his cousin - with pale blond hair that curls slightly. Even his shirt is almost the same as Scania's, though he wears his with the sleeves rolled up to the elbows as a fashion statement. The only difference is that he is shorter, as he is only a child. He wears tan slacks and always keeps a pair of sunglasses perched on his head. He almost always has a huge grin on his face, even as an infant.
