Hide a whoopee cushion on an empty square. The first enemy piece other than the king to land on it makes a rude noise and must move that same piece again on their next 2 turns. Then the cushion is done.
You draft Whoopee Cushion in either mode. Activated: you choose when to use it, and using it is your move for that turn.
As a item card, it is a one-use consumable, drafted in either mode.
