Grouse

It is a mob that lives in the mountains.
A bird with a chunky, round body, but not very good at flying.
It flies and escapes mainly when it is attacked, but it cannot fly for too long and can only fly a certain distance, so it will fly when it escapes, but it usually walks and acts.
In addition to goats, adding unique and cute mobs to the mountains will make climbing Minecraft even more enjoyable.
If you have any other good ideas, let us know in the comments.
Thank you for taking a look at my thoughts.
