Beachy isles biome

A beach biome for beach islands with palm trees and coconuts for coconut milk to use in place of cow milk! Also for food or bowls! Crabs, starfish in ponds, and a new type of fish that's yours to design?! New blocks for the palm trees that are more like a mix of bamboo design with the color of a light brown. Also some new mobs like sirens!!! Who carry good loot when killed. New villages with names like sandy village or any other you can think of! Also creating another animal of your choice native to that biome only? And a new type of sand, with news plants added on as well! This would be a great biome to enjoy for bedrock and Java both!
