Green Hill Zone (Another Time, Another Place)

The Green Hill Zone is a luscious, grass covered area of Sonic's world in the Another Time in Another Place zone.

History
Sonic has visited this zone numerous times during his adventures.

At one point in his younger years, Sonic was running through the zone not long after his latest victory over Doctor Eggman when the Time Eater suddenly appeared in the sky over the zone and enveloped the whole area in white. Later in the present day, Sonic found himself in the same white void after the Time Eater crashed his birthday party and kidnapped his friends. Spotting a portal to the Green Hill Zone up ahead, he heads through it to begin his journey to rescue his friends, as his younger self looks on from a few feet away. (SSSM: #7, StH: #230)

Next, Sonic was sprinting through the grassy plains again when he noticed the distinct lack of lite animals that usually inhabit the area. He met up with Tails, Knuckles, and Amy, who had managed to find only a little pig roaming the zone, which had told the group that it saw the other animals being rounded up into large "Metal Eggs" that got carted off into the sky. Suspecting this to be Eggman's doing, Sonic and Tails grabbed the Tornado and set off. (HCFS: #1)

Later still, Eggman appeared one sunny morning in the zone and proceeded to capture several animals and cram them into a single cage, before flying off into the sky just as Sonic showed. Using the floating platforms above, Sonic proceeded in an upward pursuit of the Doctor and his captives. Dropping the cage on the highest platform, Eggman took it upon himself to knock Sonic out of the sky with a force field surrounding his Egg Mobile, only for the field to break after crashing into too many platforms, allowing Sonic to spin dash a hole into the craft. Heavily damaged, Eggman picks up the cage of helpless animals again and retreats, leaving Sonic with no more platforms to pursue him with. Sonic reassures the animals that he'll catch up and save them. (SSD: #5)
