Mama Python 2 (Thermo Snake Sudoku)
(Published on 10. April 2021, 04:31 by peterchayward)
Inspired by I0rr-Rysdl's puzzle on the CTC Discord server.
Standard sudoku rules apply.
Additionally, the grid is completely filled with snakes: a Mama snake, 4 Snakelets, and 6 Hatchlings.
Mama snake is a palindrome.
The Snakelets are each 9 cells long. The digit on each end of each Snakelet indicates how many of the 8 surrounding cells are part of Mama.
The Hatchlings are the given thermos. Digits increase along Hatchlings from the bulb to the end. Mama snake diagonally or orthogonally touches the bulb end of each Hatchling.
Each non-Hatchling snake is 1 cell wide and may not touch itself orthogonally. Snakes do not overlap each other. There are no other restrictions on snakes touching other snakes.

I stumbled a bit on the opening, but once I figured that out, the rest was (difficult but) smooth. Excellent puzzle.
