Submarine Eggman II

Submarine Eggman Mk II is the seventh boss in the game Sonic the Hedgehog 2 for the Sega Mega Drive. This is the boss for the Oil Ocean Zone. Dr. Eggman begins the battle by emerging from oil (giving the player an opportunity to attack) and then sinking back down. Next, Eggman fires an air-borne attack spear at the player. Lastly, a gun will appear and fire three shots, the last of which will temporarily set the area on blue fire. (Both the spear and gun are attached to the submarine with long chains.) After this Dr. Eggman will rise out of the oil again and the process will repeat. Like all Sonic the Hedgehog 2 Eggmobiles, Submarine Eggman 2 takes eight hits to be defeated.

Unlike Submarine Eggman in the Hill Top Zone, Submarine Eggman II is never shown with the ability to fly (i.e. to lift itself out of the oil).
