When you think nothing could be worse, and there you have it, a flying pegomastax!!

It'll steal your sacrifices and give you fish in return!

When you encounter this but hole you want to have a pear ready or something else and wait for it to attack you that wack it.

I was attacked by one while mining flint and it stole my pick. Then it got my pike when I went to fight. That's when I noticed noticed that it didn't actually "steal" what was in my hand, but just disarmed me and dropped it in the ground. Check the ground and see if your stuff is there after they attack you. My pick was laying there near the spot of the initial attack.

The explorer note says that will flee at the slightest provocation...they will not flee at the slightest provocation.
