Warm Beach Biome

Beach biome is just some sand near the sea...But what about adding warm or tropical beach with shells a d palms with coconuts. My brother also told me his idea about adding sharks. These sharks can spawn in warm oceans near the warm beaches. It will be nice if you add some phisics like throw a coconut to crush it and get some items. Also the shells may be useful to make new armor or decorations... It will be a good update for our weird beaches we have right now, I think.
