"Confetti-itis" is the thirty-sixth episode of Viva Piñata's first season. It originally aired in North America on March 31, 2006.
Franklin has a bad case of Confetti-itis. Dr. Quackberry gives Franklin a potion that seems to be clearing up his condition. In addition, it increases Franklin’s candy capacity! Soon all the other piñatas (except for Paulie and Fergy) are demanding prescriptions from Quackberry, and are rapidly growing huge. But then they discover a rather negative side effect: their skin becomes so strong that they cannot be broken open!
- Dr. Quackberry: Here you go. The answer to all your problems.
- Franklin: My confetti-itis? Color-blindness? Broken toilet?
- Dr. Quackberry: O.K. The answer to one of your problems.
