Normal Sudoku Rules: Place the digits 1 to 9 so that each digit appears exactly once in every row, every column, and every 3×3 box.
Branches: Diagonally adjacent digits on the green branches must differ by at least 5.
Trunk: The digits on the brown trunk form a set of consecutive numbers (e.g., 1-2-3-4-5-6), but they may appear in any order (e.g., 2-5-3-6-1-4).
Baubles: Digits separated by a red Christmas bauble have a 1:2 ratio. One digit must be exactly double the other.

I enjoyed the foggy version, but the thick lines and occasionally offset bulbs made it a little trickier.
