Green Hills Zone, Sonic Wiki Zone

Not to be confused with Green Hill Zone. Green Hills Zone (グリーンヒル, Gurīn Hiru?, lit. "Green Hill") is the fourth Zone in Sonic the Hedgehog 2 (8-bit). As with all other Zones in Sonic the Hedgehog 2, Green Hills Zone consists of two standard Acts followed by a shorter, third Act which contains the Zone's boss at its end. This Zone, like the original Green Hill Zone, is filled with rolling plains of green and loop-de-loops. It also contains a couple of flip-ramps that appeared in the Green Hill Z
