It was a very interesting fight. I threw buckets of water on top of him and tried shooting him with my salt gun (I think I blinded him) but then he was really trying to jump around so I had to hit him a couple times. After four hits he was swimming lopsidedly and then on the fifth he just stopped and let himself drown. He didn't struggle at that point so either I knocked him out or I broke his skull.
Anyways he drowned peacefully after that so it was a job well done
