Rum sickness

From YPPedia

When a ship at sea runs out of rum, the crew aboard becomes rum sick. When pirate are rum sick, their efficiency in duty puzzles drops. Sea battle swordfights and rumble battles are also affected by rum sickness.

For swordfighting, indestructible rum jugs will line both of the outer most columns of the players' puzzles, shrinking their playing field in a swordfight.

For rumbling, the fists will shake, making it more difficult to aim. Further, the balls will automatically launch more often than normal if the player does not fire them.

Players on the ship will be warned that they have become rum sick with messages appearing on the screen at regular intervals while sailing, and with an alert message before the sword fight or rumble. You will also receive messages after you receive more rum, duty puzzle performance will not be completely normal until these messages end.
