Crested ibis

A friendly flying mob that is the same height as the iron golems that live in the swamp.
This mob plunges its face into the water of a swamp and pokes it into the soil with a beak.
And this mob suddenly jumps out into the sky and moves to another swamp.
Then build a nest somewhere and lay eggs in that nest.
It takes a long time to hatch.
The hatched child is then fed by the parent by the time it grows up.
As an adult, they fledge and jump out into the sky.
If you have any other good ideas, please let us know in the comments.
Thank you for taking a look at my idea.
