Minecraft Dungeons:Dolphin

The Dolphin in Minecraft Dungeons is a neutral mob added in the Hidden Depths DLC that can grant the player Dolphin's Grace if they come near it.

Behavior
Dolphins normally just swim around aimlessly, unless it is attacked where it will bite the player and attract any nearby Dolphins nearby to bite and charge the player. They can also grant Dolphin's Grace to the player when near.
