Rideable Dolphins

What if we could ride dolphins? It might sound, but really, it’s not. If you were to put a new type of saddle (Sea Saddle, Underwater Saddle, Dolphins Saddle) on a tamed Dolphins, you can ride it. It could be crafted with a regular saddle and maybe several nautilus shells and/or a Heart of the Sea? Riding a Dolphin shouldn’t give you water breathing, so players still need to have a way around that, stopping this from being a way too overpowered mechanic. Dolphins need air, however, meaning that the player will need to take the Dolphin to the surface sometimes to stop it drowning, or give it water breathing. Additionally, you could perform a jump when above the water. The Dolphin should have somewhere from 2-3x the amount of breath a player has to make the Dolphin worth it; otherwise you would be returning to the surface every minute. The player model could be ‘laying’ on the Dolphin horizontally. Rideable Dolphins would be a cool way to add a new mechanic to Minecraft, without fundamentally changing the game.
