Siren/Mermaid

Mermaids and Sirens. Mermaids should be peaceful underwater villager like creatures. Maybe even have underwater villages!!! 😁😁😁 But Sirens would be a hostile mob in the oceans. Perhaps you would hear a creepy sound from the siren and the closer you get to it the louder it gets. Then once within range, the siren comes up the water and attacks at the surface. They would be fun additions.
