The Renaissance Center’s Mind Enriching Theatre series presents a special performance of Rainbow Fish at the Anne Deason Performance Hall Saturday, to be followed by an Easter egg hunt. Rainbow Fish, based on the award-winning children’s book by Swiss author Marcus Pfister, features colorful characters, cute songs, special effects and makeup, audience interaction and a lesson on selfishness and vanity for young and old. The MET series play is being offered for school field trips through May but will be presented in one public performance at 2 pm Saturday. Tickets are $4 and everyone with a ticket from the show gets to participate in an Easter egg hunt afterwards. Rainbow Fish tells the story of a colorful fish who refuses to share one of his shiny scales and alienates all of his friends until he learns a lesson from the wise old octopus. Pfister’s series of Rainbow Fish books has been translated into 80 languages and even made into an animated series on HBO. The MET series production features members of The Renaissance Center’s theatre apprentice program and its repertory company.
