The body inhales cedar pollen, which unleashes gigantic allergens. Though U-1146 points out the creatures are mindless and non-malicious, Memory Cell claims they bring impending doom. B Cell easily defeats the allergens, but Mast Cell releases a profuse amount of histamines within the body, which causes violent allergic reactions that damage the surroundings. Just as everyone blames Mast Cell for the destruction, the body takes a steroid to treat the allergy. The steroid appears in the form of a robot that indiscriminately destroys its surroundings until it loses power. The survivors realize all of this was caused by following Memory Cell's claims and trying to attack the allergens.
