Green Hill

Green Hill (グリーンヒル, Gurīn Hiru) is a location in the Sonic the Hedgehog series.

It is a picturesque paradise on South Island with highly forested area, green fields and beautiful blue lakes. Perhaps most distinctively, consisting mostly of trees, the checkered soil floors, grass, water and with a cozy village of houses scattered across it. Obstacles include crumbling platforms and spikes in the original iteration.

"Say is it just me, or is that place we were just in look awfully familiar?"

History
Sonic the Hedgehog visited this area on his very first adventure to stop Dr. Eggman. his nephew Jack Robotnik, and his business assistant, Dr. Julian Snively, when the three mad doctors came to South Island to strip-mine and process the island as part of their plan for world domination.
