Sonic the Hedgehog 2/Oil Ocean Zone
Oil Ocean Zone is a zone where Robotnik dumps his oil
Not much to see here except those stupid flying sea-horses who shoot plasma at you, and the spikes, and those green things that blow you up to the air
Ok, nothing new, but watch out for the oil you will drown in it if you just sit there.
