The seventh zone of Sonic the Hedgehog 2 (1992), Oil Ocean swaps oil for water and overturns all the usual rules. No air countdown, no drowning, but a viscous substance in which Sonic sinks as if in quicksand and where the Spin Dash becomes impossible; green fans propel him from one side to the other. The seahorse badnik Aquis and the octopus Octus populate the refinery, over music by Masato Nakamura. At the end of the zone, the Eggmarine surges out of the oil, harpoon and laser cannon out, to be beaten in eight hits. It returns as the ninth zone in Sonic Mania.

An endless refinery, oceans of oil where you sink, and fans that propel you: Oil Ocean Zone is a striking industrial level in Sonic the Hedgehog 2. Dive into Eggman's oil slick.

Oceans of Oil

Here, oil replaces water – and changes everything. Sonic can't swim, but he doesn't drown: no air countdown, no bubbles. However, the oil is viscous like quicksand: Sonic sinks slowly, and it's impossible to perform a Spin Dash in it. Green fans propel him from one side to the other.

The oil slicks of Oil Ocean Zone — The oil slows down, swallows and rises again: it is the real opponent of the zone, ahead of the Badniks.

The Eggmarine

The end-of-zone boss is famous: the Eggmarine, a mini war submarine that Eggman conceals under the oil, only allowing its weapons to emerge – a barbed harpoon and a laser cannon. Eight hits are required. A known trick: letting yourself sink into the oil to dodge its shots.

Its Return in Sonic Mania

A triumph in 2017: Oil Ocean makes its return in Sonic Mania, where it is the 9^th zone – one of the few classic zones reimagined, alongside Chemical Plant (the two remaining distinct levels).

Oil Ocean Zone in Sonic Mania — Sonic Mania takes up the refinery again and adds mechanisms of its own, sunset palette included.

The Bestiary

Two iconic badniks populate the zone: Aquis, a flying seahorse that shoots projectiles, and Octus, a ground octopus that jumps. The music, finally, is by Masato Nakamura.
