Cave Variant, The Sea Cave.

During the new Caves and Cliff's Update trailer I have noticed that our beaches have been pretty neglected over the few years. So I propose the Sea Cave, the Sea Cave would be a giant Cave Entrance near the mountains or other biomes with large enough height, and they would have some Dripstone all around the Sea Cave and some spikes that come out from the water. And like a river, the Sea Cave would twist and wind through the caves and sometimes would go into other caves using waterfalls to go into different cave biomes. (I know this part isn't that much cave-related but I'd really like it if they'd have a new generation for the beaches including the palm trees they announced.) As well I'd like a new mob, the Sea Lion!

It would be in packs in the coves of the caves and would go into the waters to go and hunt for fish and cod in the oceans then swim back to the Sea Caves, they also have a designed purpose to give the other boots a chance to also be able to go on top of the powered snow and I think it would nullify the freezing effect if you'd fall into the snow. You'd get that from the Sea Lions shedding their fur, there are two ways, breeding and waiting until the sea lions to grow up and drop the sea lion fur or wait 3 Minecraft days to shed their fur. You'd need to combine the fur using the crafting table with 4 fur around the boots. And then your set!
