The Hydrocity Zone Boss is similar to the sub-boss in a way. As you enter the arena, the water level drops to the floor and Eggman flies in, his craft fitted with an impeller underneath and depth charges at the back. He flies from right to left above you, where you cannot reach him by jumping, but periodically lowers himself to the water, revving up his impeller. During this time, it is possible to jump and hit the front of his machine, but when he hits the water you want to be as far away as possible. Upon touching the water, he begins to draw it toward him, while slowly rising. This draws the water into a flume beneath him. If you do not move to the edge of the screen and hold this direction, you will be drawn into it. When Eggman releases the water, he moves off and the plume begins to drop. At this point the top becomes solid allowing you to leap onto it and use it to reach his machine. As he flies across the top, he will also periodically drop depth charges which, if times correctly, can also be used to reach him. After eight hits his craft explodes.
