Dolphin Jockeys

Dolphin jockeys, turtle jockeys or Drowned jockeys are mobs that won’t be added to Minecraft. This would have been a rare appearance of a Drowned (or ’Water Zombie’) riding a Dolphin or Sea Turtle in Minecraft. The only things they can ride currently are Chickens, but it is only a thing for babies, is very rare (like all Jockeys) and has no Spawn Egg or /summon command.
