Angel Island Zone

Angel Island Zone is the first zone in Sonic 3. When playing as Sonic, a somewhat lengthy introduction is played in which Sonic and Tails discover Angel Island and first run into Knuckles. In the beginning the zone looks very peaceful with green trees and water in the background. But halfway through act 1, the Fire Breath (which also appears as the mini-boss in the end of act 1) appears and sets the entire level on fire with his flamethrower. From that moment on, the level has an only-fire background, quite the opposite from the "water and green bush"-background in the beginning. The Fire Breath returns in the end of act 1 as the mini-boss.
