Hive: The Pillbug

Hive: The Pillbug is a new pair of tiles that can be added to Hive. The pillbug can move one space at a time OR it can move an adjacent unstacked piece (friend or enemy) two spaces: up onto the Pillbug itself, then down into another empty space adjacent to itself.

Exceptions:

The Pillbug CANNOT move the piece the other player just moved.

The Pillbug CANNOT move any piece in a stack of pieces.

The Pillbug CANNOT move a piece if it splits the hive (violating the One Hive Rule).

The Pillbug CANNOT move a piece through a too-narrow gap of stacked pieces (violating the Freedom to Move Rule).
