Gradius III/Stage 2

Space flight
The first wave of five arrives from the bottom, and is followed by a wave from the top.

Base
The enemy base will have watery walls on the top and bottom. You will also expect flying waves approaching from behind, in addition to the bubbles arriving ahead of you.

When you see the large blue bubble enter the screen, you may notice an enemy hovering behind you. After a few seconds of waiting, it will charge forward and attempt to steal your options.

Boss:Bubble Eye
THe stage boss is slightly weaker than the previous one.
 * It inflates a bubble on its top or bottom, then breaks it into three smaller bubbles. These smaller projectiles bounce off the top and bottom of the screen.
 * Occasionally, it will create a bubble on the front. This can be destroyed without ill effects.

To damage it, aim for the eye. Your shots will gradually drill a hole to the eye, allowing you to get a clear hit on the core.
