S02:E19 - Ignatius Finds His Voice | Changing Twins

Ignatius sings horribly off key! In an attempt to teach him how to sing in tune, the two cousins lead the superintendant into a magic cave which, in fact, is the casting studio for the Valley Concert Choir, directed by a Voice-Borrower Plant... | The twins are fed up with being confused with each other all the time. They look for a magical way to differentiate them-selves in the Secret Notebook. And find the Personality Tuner, but they use it backwards, and end up very out of tune with each other.
