It's possible there's a lesser-known animated musical with that title, or perhaps you're thinking of a different title or a different type of media altogether.
To help me understand what you're thinking of, could you provide more context?
* What type of animation are you thinking of? (e.g., 2D, 3D, stop-motion)
* What is the general theme of the musical? (e.g., historical, fantasy, comedy)
* Do you remember any specific details about the plot or characters?
The more information you can give me, the better I can help you find the answer.
