New mob the celestial phantom

The celestial phantom is a bright yellow neutral version of the phantom that spawns near floating islands the islands will have a new tree called celestial oak that has yellow wood and instead of apples it drops golden apples. But back to the celestial phantom it would only hurt the player if attacked and be immune to sunlight damage it would also attack regular phantoms it could be tamed with golden apples. and finally it would leave a yellow particle affect trail behind it as it flies. This would be a good addition to Minecraft because it shows the good and bad sides off mobs.
