Fancy Nancy and her friends Bree, Rhonda, Wanda, and Lionel are going to be performing in their very first show, “Deep Sea Dances.” Nancy is positive (that’s fancy for 100 percent sure) that she and Bree will be picked to be mermaids. When another girl wins the coveted role of the mermaid, Nancy is stuck playing a dreary, dull tree. Can Nancy bring fancy flair to her role, even though it isn’t the one she wanted? This 50-minute show manages to entertain both adults and children in a masterful way.
