Sonic Unleashed Easter Egg - Spagonia's Lively Citizens

In the Spagonia Night Town Stage, from where you start from selecting it by the world map, go to the alley nearby on the right. Close to the entrance you came from, stay on the left side and examine the first few feet. Somewhere you'll hear a boy whistling a tune. This is very faint so you might want to be somewhere very quiet. This little boy is Sonic whistling the tune from the Sonic Unleashed Teaser Trailer, the first trailer ever released for the game. Another voice was found as well. Further on into the alley, next to the very lit up window on the right, you can hear a whole group of people talking (a grown up woman, a grown up man, a little boy and a little girl). My prediction is that it is a family probably having dinner. You can hear this much more clearer than the whistling. The voice also seems haunting and eery. It may also be a spirit. Who knows. But what ever it is, these Easter Eggs were very shocking and suprising at first. Enjoy.
