I remember in one of those "multiple stories in one" episode, there was this condition that alters one's voice, i forgot what it was called and i forgot what episode it was. Do you guys know which episode was it. I remember Tamama first having it and his voice was deep! Keroro was infected next, then the others but Giroro. Giroro had a high pitched voice. I wanna add that to the wikia and add it to the conditions category.
