Rhincodontidae or Jinbe

A large friendly mob that appears in the warm deep ocean, and is characterized by high physical strength.
It is usually characterized by slow swimming, but if attacked, it will escape quickly.
However, it cannot be caught in a bucket and cannot be boarded in a boat or minecart.
Of course, you can't use reeds either.
The main reason is that the body is too big, but another reason is that it is designated as an endangered species, especially now it is in danger of extinct in the wild.
Therefore, it is impossible to catch.
It's perfect for Minecraft, which adds endangered animals such as pandas and axolotl.
I think it will inform people all over the world about the existence of this friendly fish.
Thank you for taking a look at my idea.
