Sick is a status ailment in Mario & Luigi: Bowser's Inside Story. Certain enemy attacks, especially those from Blizzard Midbus and the Sniffle Thwomp can cause Bowser to become Sick. He will glow blue around him and a runny nose. Every turn, Bowser will sneeze and lose a chunk of HP 15, 30, 60, 75, 90 or even 120. Much like Poison, although Bowser is the only one who can get Sick and he cannot be poisoned in the traditional sense.
