Ok folks. I received this from Gaby:

This is soo funny ro read...ähem, I am German but never heart about that tradition and I am not sure what a pickle is??? Can you descibe it????
So I did some more investigating. What did I find? Well according to Wikipedia, along with some other sources, I found this:
A Christmas pickle ornamentThe Christmas pickle is a pickle-shaped ornament hidden in the tree. The child who finds it first on Christmas morning receives an extra present. While the Christmas pickle is believed to be a German custom, it is fairly unknown in Germany but widely spread across the USA. In fact it is completely of American origin. 
So what I thought was a nice German tradition, was actually a hoax. But it has become my tradition. And I will continue the tradition, but probably will leave the German part off!
