A band of Vibrio bacteria invades the stomach. Basophil warns the immune cells about it, but confuses everyone by speaking cryptically. The immune cells defeat the invaders, but one of them, Eosinophil, was unable to land any good hits and had to be rescued. The other cells mock her as a weakling, except AE3803 and U-1146. The stomach then gets invaded by a massive Anisakis parasite. The immune cells are no match for it, but Eosinophil explains she is designed to battle parasites and kills it with a single stab. The other cells apologize for making fun of her and praise her as a heroine.
