A ballet class of mice perform "Swan Lake." As with any ballet recital, if you're kid isn't on stage, who cares?
The book attempts to hold children's attention by having lots of a few life-the-flaps, one very unimpressive pop-up, and many little pockets and envelopes with little paper props and letters inside. That none of the stuff is torn or missing shows how little my daughter came back to this book when she was young. She found it meh too.
