Calamar hostil , Cangrejo , Pingüino

We know these mobs, which have been lost in previous mob votes, so I thought it was the perfect time to add them, since Mojang is incorporating into the game some mobs that they have lost years ago, such as frogs and copper golems. In addition, the next drop is essential since additions or changes to the aquatic aspect are taken into account. So it wouldn't be a bad idea to bring these mobs back to life; you could say they are closely related to the next update, as well as giving more variety to the ocean. Each mob could continue with the functions that were announced when they were presented: "The hostile squid" could drag us to the seabed, "The crab" would be very interesting, a neutral or decorative mob in the different biomes where it would generate, its drop will be the one that will be very useful, (its claw), it would give us an extra range when building or pvp, "The Penguin": flightless seabirds that are highly adapted to life at sea, so it would be a very good idea to add them and give more life to the icebergs, its function could be different from what was presented the first time
