Sick

Sick is a status ailment in Mario & Luigi: Bowser's Inside Story and its 3DS remake, Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. Certain enemy attacks, especially those from Blizzard Midbus, sleeping Naplocks, and Sniffle Thwomps can cause Bowser to become Sick if they hit. When sick, Bowser glows blue around him and has a runny nose. Every turn, Bowser sneezes and lose a chunk of HP, ranging from either 15, 30, 60, 75, 90 or even 120 HP. It is much like the poison status effect that Mario and Luigi can be inflicted with, although Bowser is the only one who can get the Sick status and he cannot be poisoned in the traditional sense.

In Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, the ailment disables Bowser's ability to inhale. It also disables the command to press when using his flame ability.

Trivia

 * A Sniffle Thwomp begins battles while sick but it does not actually have the status effect, even though it does take damage every turn and can make Bowser sick or poison Mario or Luigi with its attacks.
