It's "Yankee Doodle Dandy!" :D "Yankee doodle went to town, riding on a pony. Stuck a feather in his hat and called it macaroni!" It was originally published as an insult to American colonists in the 1700s, but now is considered a patriotic song for all Americans, especially in Connecticut. I could actually see you going somewhere with this, though. The cute, simple melody line is fitting for a videogame, and it has a strange energy to it as well. It loops well, too. Not much else to say - it is only 7 seconds long - but maybe you could elaborate on this melody, even if it is almost 250 years old! ;)
