It looks like Harry's friend and the gamekeeper and Keeper of Keys and Grounds of Hogwarts has a Christmas tree for you!
Naturally, Rubeus Hagrid stands a bit taller than most Pop! Vinyl figures (about 6-inches, to be more precise), but like them, he comes in a window display box.
This Harry Potter Holiday Hagrid 6-Inch Pop! Vinyl Figure would make a marvelous addition to your deco, so order him while you can!
