A use for bats

I think backs would hang around caves the warden especially and possibly witches and when awoken they will follow around a hostile mob especially clinging to the warden or a witch if they are there they will go to them over any other mob when you are hitting the main enemy ( not the bats) the bats will try to swoop down and get in front of your attack to block it and they would drop bat wings which you would just put 2 bat wings plus 1 arrow to create a long flight arrow it is an arrow that can fly further. Thank you for your time and listening to my idea!
