Dolphin Breeding/Behavior enhancement

Feature: Dolphin behavior after being tamed to be similar to dogs in the protection of the player after being attacked by a hostile mob/player and in assisting to attack other mobs when the player hits the other mobs. Naturally the dolphins would stay in a body of water.

Suggested way to apply in game: upon taming by the use of Raw Cod or Raw Salmon this effect would begin. Effect would continue till the death of the Dolphin.

Additional feature for Dolphins:
The ability to breed dolphins would be a fantastic feature added to the dolphin behavior/breeding system (similar to the breeding of dogs.) To be able to grow the pod size of dolphins. Also making it possible for the first feature (protection of player) mentioned to have a lasting effect.

Suggested way to apply in game:
2 dolphins are fed (perhaps 3 raw Cod/Salmon per animal totaling 6 fish) in at least a 5x5x5 block area of water source blocks thus causing the dolphins to enter love mode and create a baby Dolphin. Which would grow to be a pre-tamed Dolphin(similar to the dogs and cats already in game)
