It's surprising how much a change in music can help a transformation be more interesting. It's not a major improvement to the transformation as a whole, but it does help to make it less underwhelming. I don't find Polymouse's original music too generic, and it's at least clear with a unique-ish tune, unlike other transformation themes. But it is much too quiet, needs a better ending, and doesn't help with how underwhelming Polymouse's transformation is.
