Introduction now occurs when the pawn moves away. This includes very many variants with different external pieces. I have tested the Camel in this context, too. The Camel is interesting while it can be exchanged for two pawns, thus breaking up the position. Zillions does this often when playing against itself. The players, in their first move, decide from which file they aim to introduce the external piece. In this case, the external piece has previously been positioned on the knight file. It is introduced to g2 when the knight pawn moves. Black introduces his piece when the bishop pawn moves.
