Squatina

A neutral mob that appears in the deep ocean and can be caught in a bucket.
I usually like to be on the seabed.
However, unlike a normal neutral mob, it only counterattacks as much as it is attacked.
For example, if you are attacked once, you will counterattack only once, but after you counterattack, you will not do anything, but the attack power is very high, so if you catch it with a bucket, you should catch it carefully.
If you have any other good ideas, please let us know in the comments.
Thank you for taking a look at my idea.
