The Oasis- Hope for desert dehydration

The oasis would be a rare “structure” in the desert, at the oasis there would be a new kind of tree (palm tree) with a new kind of wood (palm wood!) Inside of this tree, there would be coconuts! You can eat them alone or you can throw them at a stone-adjacent block to break it in two to drink it like milk (would offer a little extra hunger) not only would there be a new tree, around the oasis there would be new grass and plant-adjacent blocks, inside the oasis there would be a new fish mob (the name is up to you) that can be killed and cooked for a food source as good is cooked pork chop
