— Description from the Instruction manual.
Green Hills Zone is the fourth Zone in the Master System and Game Gear game Sonic the Hedgehog 2. The name is a reference to the Green Hill Zone from the original Sonic the Hedgehog, which it also heavily resembles. As with all other stages in Sonic the Hedgehog 2 (8-bit), Green Hills Zone consists of two standard Acts followed by a shorter, third Act which contains the Zone's boss, Mecha Pig.
This zone, like the original Green Hill, is filled with rolling plains of green and loop-de-loops which Sonic must defy gravity in order to speed around. It also contains a couple of flip-ramps that appeared in Green Hill Zone of Sonic the Hedgehog (8-bit). Pretty much the only difference comes from the trees, which seem more of the deciduous variety than the usual palm. Nevertheless, it seems likely that Green Hills is supposed to be the same place as (or at least a sub-region of) the original Green Hill, as both Zones are sited on South Island, and they are almost identical.
The boss is a robotic pig with an inexplicable penchant for sumo posturing. Sonic's porcine adversary will curl up into a ball and either roll or float from one side of the screen to the other. When he unfurls, that's your chance to hit him.
- The stage's music was remixed into "Sonic - You Can Do Anything", the Japanese/Europe intro theme of Sonic the Hedgehog CD, and was also the music for Mecha Green Hill Zone in Sonic Chaos.
- Green Hills' position as the fourth level is somewhat surprising, because the easy platforming (as well as its several opportunities for maxing out Rings and collecting extra lives) would make one expect that (as usual with Green-Hill-themed zones) this level would come first in the game.
- In the Japanese manual, the katakana for this zone directly reads "Green Hill", suggesting that Green Hills may possibly be a typographical error on the part of the developers.
- But it can't be, because Green Hill Zone from Sonic 1 (Both 16-bit and 8-bit), is completely different from Green Hills Zone in Sonic 2 (8-bit only), especially when there's no Palmtrees in Green Hills Zone.
