Labyrinth Zone boss

The Eggmobile is the boss of the Labyrinth Zone in Sonic the Hedgehog. It is piloted by Doctor Eggman.

Unlike the other bosses in the same game, this Eggmobile is unmodified and possesses no weapons. Eggman merely uses it to escape the flooding tunnels of the Labyrinth Zone. Sonic does not actually need to hit the Eggmobile in order to win the level. He merely follows Eggman through an ascending passage filled with poison-spitting statues and tridents, while at the same time attempting to stay ahead of the rising water level. There are no air bubbles in this section of the level, and if Sonic becomes submerged it can be difficult to recover ground.

Once Sonic reaches the top of the passage, Eggman will fly away, past the Zone's Egg Capsule, which Sonic can open to complete the level.
