Normal 6x6 Sudoku rules apply.
ARROWS - A digit on a pink arrow is the number of steps to the nearest cell in the indicated direction that contains an Invisible Pink Unicorn. (A unicorn can't be on the arrow, since that would put a 0 on it).
INVISIBLE PINK UNICORNS - Invisible pink unicorns don't do anything. But they definitely exist.
Solution code: Row 3

Fun puzzle! Could someone explain the solution text?

If something exists, does that not count as doing something? :-)

I'm not sure how hard it'd be to set a full 9x9 sudoku with this ruleset, but I would definitely give it a go!
I went into thinking "This can't work!", then had my mind blown!
And then scoffed at the legend reveal at the end, thinking the joke was "Maybe the legend was misheard over time...", as legends often are, and figured it ended there.
But then I saw PersonWhoExists50306's comment after I put in the solution code, and went back to double-check, and had my mind blown a second time!

I was concerned about a moment of uncertainty I had solving this puzzle, but it turns out that learning a little more about these fantastical creatures really resolved it for me. Fantastic puzzle idea!

I really need to read the directions more carefully. One word to which I failed to pay sufficient attention, and it all fell apart.
Great puzzle.

Thank you very much for creating and sharing this funny puzzle. But - how on earth do you know that the unicorns are pink?!

juggler: We know scientifically that they are invisible, because we cannot see them, but we must have faith that they are pink.
