Volcano Biome/Underwater Volcanos

Volcano biome(s). With volcanos in real life being under water, on beaches or in greenland moutains, I think a biome that is either on a beach surrounded by new *palm trees and coconuts maybe as well*, or an underwater volcano feature might be neat. I'd say greenland volcanos, but, the moutains have been updated lately a lot more than the water or desert biomes. I think new trees are always great, plus a new item like coconuts could also be a great feature to go with a volcano update! Also, maybe a new mob? To suite the biome? Maybe a new boss, or a lava golems, or trolls? Maybe even a cute coconut object pet type of thing? That could help players find treasures? I think this a volcano update could be a great introduction for lots of other fun items as well! I don't think an explosive feature would be all that necessary either, considering lots of volcanos remain dormant for long periods of time.
