Oil Ocean Zone is a location in the . It appears in and is the remains of where Dr. Eggman attacked a part of the Metropolis; this caused the sewers of the Metropolis to splatter out of the city and rise. The results formed Oil Ocean Zone; the sewers do exist to this day and were a playable stage in under the name Aquatic Mine.

==Sonic Heroes 2==
Oil Ocean Zone makes an appearance in Sonic Heroes 2.

This is in direct clash to the developed Metropolis.
