    Are you sure this is a mate in two?

    Can't see how black can manage check, let alone mate.

    It is c3 or e3 followed by c2 or e2 respectively? Only works if white had just played c4 or e4.

    Black to move and mate in 2
    I think that the idea is to secure the d-2 pawn so to keep the white king stalemated. And then mate him with one of the knights. Now we secure the d-2 pawn with the king and let one knight be taken and maneuver the other one till we mate. But I can only do it in four moves.

    So I have to ask you: is this black to move and mate in two pairs of moves?

    No, it isn't two pairs of moves. It's a normal mate in 2.

    Question for the class: What are all those pawns doing on the board? Is it just for the sake of looking more Christmassy?

    In that case is it white to move then?

    Yes, but as you pointed out, that only works IF the last move was c2-c4 or e2-e4. You must prove en passant is legal before you can use it in the solution.
