3 - 6: The Common Cold

When Dan finds himself sick with a cold for the first time in his life, he vows revenge against the viral invaders infecting his body! After tracking the source of his sickness to none other than Ninja Dave and learning that physically fighting him won’t cure his cold, Dan realizes that he is going to have to fight this battle within. But none of the typical cures work, so Dan decides he has to take this to the next level. He heads to the Department of ControllingDiseases for some high tech bio-weapons and suddenly finds himself at the center of a battle with an ex-supermodel turned spy bent on biological warfare.
