The Dokudoku Pakkun Flower spread the Gahaha Virus onto the Mushroom Kingdom.

Peach and Daisy affected by a stronger dose of the Gahaha Biyō.

The Gahaha Biyō is an illness provoked by the Gahaha Virus in the Dr. Mario manga.

To conquer the Mushroom Kingdom, Bowser creates the persona of Gahaha Daiō and creates the Gahaha Virus and spreads it, with the help of the Dokudoku Pakkun Flower, to the Mushroom Kingdom citizen. In action, the Virus causes the infected subjects to laugh uncontrollably, and with a stronger dose this can lead to the death of the patient. Mario manages to cover his mouth and his nose, during the first spread, saving himself, and wearing his lab equipment, goes in search of a cure, finding a mushroom that repels the virus, the Miracle Kinoko. During his search, Bowser try to serve him an apple filled with ten doses of Gahaha Viruses, but Princess Peach and Princess Daisy eat it instead, almost dying of asphyxiation because of that.

One singular virus survives the purge, so Bowser powers it up by splitting in three Viruses immune to the cure and they infect Luigi, by producing walls of Gahaha Viruses that will lead to death in six hours. Their variant of the disease still makes the infected laugh, but also influences his movement and his emotions (whoever, the latter is not a direct cause, it is just the Viruses kicking and hitting his cerebral nerves). To cleanse the virus, the Miracle Kinoko does nothing, but by aligning four elements of the same color, the Gahaha Viruses can disappear. With this, Dr. Mario manages to save Luigi. When the three Viruses are kicked out of Luigi, they hide in Bowser's mouth, infecting him.

In his last attempt, Bowser try to use another batch of Gahaha Viruses at the Mushroom Kingdom stadium, by trapping the crowd inside and promising to opening it and infect everyone once again if Dr. Mario does not win his challenge, but Mario comes out victorious and both Viruses and Gahaha Viruses are punched into the sea.
