Stars? Angels? LAAAAAAAAME-O. Those are out this year, because the ONLY thing that should be on the top of your Christmas tree is Groot. Artist Wolfen Moondaughter (Damn is that a hell of a name or what?!) created this custom Groot tree-topper and man, is it glorious.
I suppose if you wanted to really step it up, you could capture a live raccoon and put it in the tree, but ya know, the whole rabies thing.
