Ocean Update to make Minecraft's oceans more awesome.

Hello Mojang, I have gotten this amazing idea for an ocean update! You can name the update anything you want, if you decide to make this update. We have the kelp forests in Minecraft, but there is something missing still: the Sea otters! These animals are known to live in real life kelp forests, so why not add them into Minecraft. Sea otters would be found in packs from 3-5 with a possible baby. The mob would be passive, only attacking a specific mob. Sea otters are known in the real world to eat sea urchins, so I had the idea to add sea urchins to this possible update. The sea otters would attack sea urchins if the two mobs are in a ten block radius near each other. The urchin if killed would possible drop a sea urchin item that is not edible, but would be able to craft into sea urchin armor for players. Each armor piece gives one protection, all though if you ware a full sea urchin armor set you gain the thorns enchantment. It goes away if you take off any of the armor piece. Now let's go back to the sea otter, I think if the sea otter is killed it could drop either: a sea urchin or a cobble stone block. It could drop a cobble stone block because sea otters are known to use rocks to crack open hard food. Thanks for reading my suggestion for a Minecraft update!
