Angelina and her grandparents are traveling by boat to the Mouseland Dance Festival! Angelina can't wait to perform, and she's so busy practicing her steps that she has little time to help her grandparents with all the work that needs to be done on board. When she disobeys her grandmother and ruins her festival costume, Angelina's is devastated--until Grandma shows her what it truly means to be the star of the show.
