If you've already mastered the Hive, it's time to introduce a new member: the Pillbug. This expansion adds a pair of tiles that completely shake up the game's positioning dynamics, introducing a manipulation capability that can either save your skin or wreck your opponent's plans. The Pillbug isn't just another piece; it's a movement facilitator.

Basically, the Pillbug can move normally, one space at a time. But the real trick lies in its special ability: it can take any adjacent piece (friend or foe) and 'jump' it over itself into an adjacent empty space. It's like giving a strategic nudge to reorganize the battlefield. But hold on, it's not all fun and games! There are strict rules to prevent abuse: it cannot move the piece the opponent just moved, nor can it move pieces that are already part of a stack. Furthermore, the move cannot break the fundamental 'One Hive' rule or violate the 'Freedom to Move' rule.

The most critical detail is the post-move 'paralysis': any piece physically moved by the Pillbug becomes immobile on the next player's turn. It cannot move, be moved again, or use its special ability. That's the price for the free ride! For those who love chaos, remember that the Mosquito can mimic the Pillbug's abilities, even if the Pillbug itself has been rendered immobile. If the Pillbug is pinned under a Beetle, it remains trapped just like any other piece. It's the perfect dose of extra complexity for those looking to deepen the base game's strategy.
