Fish

Fish is one of four bosses that can encountered within the Maintenance System. It is an evolution of the Fish enemy type.

The battle takes place within a room containing water. The height of the water varies, depending on the attack being used by Fish. Water height will always update to match the next attack before it starts.

Attacks
All blastcores in Fish's fight will detonate into eight evenly spaced shots, instead of the normal six. Cardinal shots will be mid-sized while diagonal shots will still be large.

In the following attack descriptions, Fish refers to Fish (Boss), while normal Fish enemies will be specified.

Fish's movement is largely tied to its attacks. When offscreen, it positions itself to do its next attack from whichever side is closer, except before and after it attacks from below.
