Steelhead

Their bodies are large and covered in hard scales.

They inflate bombs above their heads and throw them at their targets.

They generate the bombs above their head using stored explosive saliva.

The tube at their mouth goes to the top of their head, and they repeatedly pump saliva through the tube.

They use hanging seaweed to block out the strong sunlight of the Spirhalite Islands.

Their equipment has gotten damaged by the salty air.

While Steelheads are building up energy in their bombs, attack the bombs.

When defeated, Steelheads explode, dealing heavy damage to nearby Salmonids.

It takes time, but you can defeat them by continuously attacking their hard bodies.
