|Marine Ocean Zone does exist, and it can be found in real encyclopedias. You may read more about it here:|
Marine Ocean Zone is a conjectural term used by Marine the Raccoon to describe the three adjacent water based zones Aqua Lake Zone, Troll Bridge Zone and Aqua Planet Zone on which she operates in Sonic Heroes 2. The names of these zones originate from Sonic the Hedgehog 2, Sonic the Hedgehog and Sonic Chaos.
Aqua Lake Zone
Aqua Lake, born a natural beauty spot, has its side of the bridge decorated with bogus waterfalls, fountains and a plethora of aquatic tributery. North Aqua Lake is used as part of Resort Island, a Babylon racecourse.
Troll Bridge Zone
Troll Bridge Zone is a series of bridges linking Green Hill Zone and Jungle Zone to the north and south and splitting up Aqua Lake and Aqua Planet on the west and east. Although there are several bridges at the northern end of the zone there is only one bridge which allows access to Jungle Zone and underneath that bridge lives the execrable Guidashir Jahandambelis, a cliché troll who gets a bit tasty whenever anyone tries to pass through. Any team who plays Troll Bridge Zone gets a piece of Guidashir.
Aqua Planet Zone
Aqua Planet is the other side of Marine Ocean left to rack and ruin by man. Instead, this half plays host to diffused ruins from Mecha Green Hill Zone and Electric Egg Zone and most, if not all, of the water is contaminated, making it an ideal habitat only for Team Badnik (who actually prefer Electric Egg Zone).
