Frogs are very active in our garden pond at the moment, inspiring this puzzle.

RULES
Normal anti-knight sudoku rules apply. Digits (1-9) may not repeat in rows, columns, regions, NOR a chess knights' move away.
Additionally:
- Adjacent digits on a green (german whispers) line must differ by at least five;
- Digits on a purple (renban) line must form a non-repeating, consecutive set (in any order);
- A black dot between cells indicates that their digits are in a 2:1 ratio;
- A white dot between cells indicates that their digits are consecutive;
- Note that not all dots are shown.
Solution code: Please enter the digits of the first row (left to right).

accidental bifurcation here... missed an option (ruled one out by mistake) for the black kropki [always a great start if one isn't able to count properly in a sudoku puzzle LOL]
Aaanyways, once that hit a wall I clicked the restart button and knowing it's "not that" ... it feels like I cheated tbh.
But I liked the puzzle :D

I'm a really bad judge of difficulty but I think that this is a fair bit harder than my usual sudoku.

Very hard puzzle. I got confused by the eyes of the frog, that look like a white dot, but actually are not and can not be that. There was a trick that came back a lot that I liked, but was hard to spot. Many steps were very hard to find for me. In the end, after almost 3 hours, I lucked into the solution by a long bifurcation chain. Thank you for the puzzle.
