Stories of Magic: Popo Baa the One-Eyed One-Winged Batman

I've heard several versions of this story, all of which are short on details but all agree that it's a raping batman.

There is a man with one bat wing and one eye, and his name is Popo Baa, which means Disastrous/Calamitous Bat.  He is a rapist.   He only (or usually only?) rapes small boys.  If Popo Baa comes to rape you he may move into your house.  The only way to protect yourself or get rid of Popo Baa is to tell everyone you know about Popo Baa and possibly to invite everyone you know over to your house while Popo Baa is there, and eventually Popo Baa will move on to his next victim, which (I think) is usually either someone you've told or someone you invited to your house.
