Sharks don’t really pee. It gets stored it in their body tissue instead. Part of the preperation of shark is essentially pressing it for weeks to bring out the ammonia and let it break down into something that won’t kill you. Doesn’t taste good, but won’t kill you.
I found it easier to play with bots to learn, they are more forgiving and are a bit bad at the game as well.
