Actually no.
I am really interested in folklore, I know some chinese, japanese, russian, and other folklore tales, but german?
I only remember some creatures...
Like the "Hanghuhn" wich would roughly translate to "hillside-chicken".
It is told that in regions where there are many hills and rivers, the farmers had those animals wich would look like normal chicken, but one of their legs would be much longer so they could easily stand on a slope of a hill. To catch one of these you just have to stand behind them and call them, as soon as they turn around they would fall over because of their different sized legs
Then the german version of the american "Boogeyman" would be the "Nachtgiger", "Nacht" means "night" and "giger" is old german for "kriechen" wich would translate to "crawling" or "creeping".
But some say that "giger" comes from an old word for "rooster" and so they say tht the Nachtgiger would have the wings of an rooster.
He is told to creep around in the night in villages to catch children that wander around in the dark, to drink their blood.
And then I remember the "Winselmutter", translation would be "Crying Mother", well "Winsel" is an old word for "crying" or "sobbing".
And that would be a white clothed or even white glowing old woman that would be crying all the time. As soon as you see one of them it would mean that someone you love is going to die or something bad happens to you.
In houses where someone lies with a serious disease you would eventually hear a Winselmutter, or even see one, sitting in a corner of the room, sobbing.
That's all I remember and I am really not that found of german folklore, you don't hear, read or see german folklore anywhere these days. It's weird, hard to find.
Hope I could tell you something interesting though
