"Don't be a fool Mr. Baggins if you can help it; he is a skin-changer. He changes his skin: sometimes he is a huge black bear, sometimes he is a great strong black-haired man with huge arms and a great beard. I cannot tell you much more, though that ought to be enough."

Normal sudoku rules apply.

Begin by writing in the "tree" digits in boxes 3 and 7 from the previous puzzle.

Digits in cages do not repeat (though their values can); their values must sum to the given total.

There are 9 "changer" cells (digits 1-9 once each) in the grid; one in every row, column and box. There are also 9 "victim" cells (goblins, most likely) the digits 1-9 once each; one in every row, column and box. The value of a changer cell is always 8; the value of a victim cell is always 0.

The 8-changer cell is given in box 5; the solver must deduce where the remaining changer cells (and all the victim cells) are.
