@Eddnom it's from the movie House Shark, the babysitter is pulled down the toilet and somehow the fin is popping out
in the same way becausee why not. The movie is complete garbage, would very much recommend.
I'm waiting for some Ouija Shark references personally.
With that shark, it's not a question of what happened to the hostages. It's more like: 'You mean some of them were not vic- ahem, I mean targets? I didn't notice.'
