Rules:

After it gets dark Nala loves to go outside and look for new friends in our backyard. Will she find one today?

Normal Sudoku rules apply.

Numbers on a thermometer strictly increase as they move away from the bulb towards the tip. There is only one tip for each thermometer and each thermometer has its own color. Elements of the same color are connected.

Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all possible dots are given. (There is no negative constraint.)

Additionally the grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.
