Why settle for one Dr. Seuss book coming to virtual life — in, say, a DVD of The Lorax — when you can have a whole library of them come to real life onstage? That’s what happens in Seussical on Sunday, April 28, when not just the Lorax, but the Cat in the Hat, Horton the Elephant, Sam I Am, and that guy who has all the trouble getting to Solla Sollew collide in a wild and crazy adventure with songs, dances, and general mayhem. It’s the final show in the Not Just For Kids series, which features family-friendly professional performances in the beautiful Michigan Theater. This is the series’ biggest show to date, featuring 13 professional actors. “These shows make such a great first theater experience for younger kids,” says Emily Mathews, head of the theater’s marketing. “And adults have a blast, too.” 1:30pm. $12 per ticket for members, $15 non-members. Tickets at ticketmaster.com and all Ticketmaster locations. 1-800-745-3000. www.michtheater.org.
