This is a common trick puzzle, because it appears in a semi-famous book, but is it possible for this position to be reached with white to move?

It is possible, white knight comes out, black's pawn comes out and if its not the desired player's turn, black's king can come out and perform triangulation and go back

That's a good thought.

Here's some old content which will be new to many of the readers here. Why is this position illegal? (If you've already seen it, please don't spoil it for the newcomers.)

That's a good puzzle. You'd think with all those black pawn tempi, there would be enough time to unravel white's back rank, but you'd be wrong.

If the a-pawn was on a3, the following last moves show the position is legal:

The black DSB could have been captured by the wP currently on f7.

I forgot to switch parity oops the other black knight should be out instead of inside

And a lot of other moves that basically blunder your position.
