Contents
Instruction Manual Description
Robotnik's refineries are pumping at full steam. Crude oil has turned the ocean black. Can Sonic keep his footing on the slippery catwalks and bursting steam vents?
Enemies
- Octus - Octopus enemy, levitates and fires a missile when Sonic approaches.
- Aquis - Seahorse enemy, floats around quickly, firing globules of oil at Sonic.
Differences between Wai beta and final
- The sun scrolls with the background, and is non-animated.
- Wooden balls are embedded in the ground, and can be activated by pressing a nearby switch. They will pop up and move to the left at a fixed speed. Sonic can stand on these balls while they travel. They were dropped as a gameplay element from the final, possibly because nobody could think of a good use for them, but the chambers and switches can be placed with debug mode, and both have the same behavior as in the beta. Wooden balls were seen in prototype shots of Sonic the Hedgehog's Green Hill Zone, and can be seen in this game's debug mode, but they cannot be placed.
- Two seahorse enemies are found within the prototype ROM through hacking.
- An unused, shoot-and-flee octopus enemy is found within the prototype ROM through hacking.
- The oil splashing animation is missing and oil slides have no effect on Sonic.
- A pipe in the level's background is sucking oil up instead of pouring it out.

Technical notes
Oil Ocean's "sinking pool" mechanic was reused in Marble Garden Zone, though it's not nearly as expansive there.
In this zone, the ground is supported by numerous small pillars that extend down to the oil, but not all the way. Because of this, the player can spindash in the oil while standing against one of these pillars to go under it. In this way, it's possible to travel at the very bottom across the whole stage.
