You were swimming, when suddenly a boat came along. They sent a harpoon down, it injured your side, making you pass out. You woke up in some place, it didn't look like the sea, there were no fish, some seaweed growing on the sand, and this really big skull, it didn't seem to be made out of real bone. You had seen a very large merman, he was a shark mer. You were scared of him, so you hid, you managed to squeeze through the eyehole to hide. "Hm..." he says, sniffing after smelling your scent.
