This expansion adds two pieces: a black woodlouse and a white woodlouse.
The woodlouse, like the queen, moves one square at a time. However, he can really change the course of the game: Instead of moving, he can take a piece adjacent to him and move it around him.
To do this, he moves the piece up on top of him, and places it around him on a free square. He cannot move a piece that is already on another piece. The moved piece cannot be moved on its next turn.
