Today's Puzzle:

We've played similar puzzles in style to this, but they've usually been much harder puzzles than what Sir Moose has devised for us for this Monday morning 😀

Rules:

Place 8 of the digits 1-9 into the sudoku grids. Digits cannot repeat in any column, row, or 2*2 box, and the left puzzle and right puzzle each have 4 unique digits.

Digits on an arrow sum to the digit in that arrows circle.

Digits increase from the bulb of the thermometer.
