Hive: Mosquito expansion
The Mosquito pieces can be added to a standard Hive set and are placed in the same way as other pieces. Once in play, a Mosquito can take on the movement ability of any creature of either colour that it is touching at the start of its move (a stack with a Beetle on top counting as a Beetle for this purpose), thus changing its movement characteristics throughout the game.
Exceptions: If a Mosquito is only touching another Mosquito at the start of its move, it may not move at all. If a Mosquito is moved as a Beetle onto the top of the Hive, then it continues to move as a Beetle until it climbs down.
Please note the original Hive game is needed to play with the Mosquito Expansion pieces.
