Mia and Me (2012)

S1E19 The Panned Piper

Mia finds herself paired with Violetta for a science project, which frustrates her greatly. Violetta, confident she can manage alone, dismisses Mia’s sincere efforts to collaborate. While Violetta appears to be planning to cut corners, Mia's thoughts are consumed by troubles in Centopia. Phuddle has invented a peculiar instrument: a calliope that captivates all who hear it. Unfortunately, this enchanting music is drawing unwanted interest from dubious characters.
