Oops, sorry, that's right. Nc6. And then...

1. Nc6! Kxc6 (if the king doesn't take the knight, both pawns are lost anyway through some combination of knight forks, x-rays and straight captures)
2. Bf6 Kd5
3. d3! a2 (if the king moves, he either gives up the d-pawn or gives up the a-pawn by x-ray)
4. c4! dxc3 (enpassant, if the king moves, well, you know what happens)
5. Bxc3 (covering the promotion square a1)

After that, the black king doesn't have much to do except get in the way of white's d-pawn, which will eventually promote.

Doesn't Be6+ also work. If king takes then Nb5+ and clean up the pawns. I didn't look past that but I assume it's winning.

We must have the same disease. e6 is a white square, so the bishop can't go there.

"if the king moves, well, you know what happens"

just to exlicit that
if black plays
4. ... Kc5 (instead of the en passant)
5. Kb7!
is necessary
if black moves its King to avoid checkmate (Be7++),
white will take the pawn on d4 & intercept the other
