Tartaglia, who will be joined by the stars of the show, puppets Dorsel, Bubbles and Tank, will meet and greet fans, sign autographs and perform songs from ImaginOcean.
Gymboree is located in Manhattan at 327 West 14th Street.
As previously reported, the final performance of ImaginOcean at New World Stages will be Sept. 4. The production will then launch a national tour that is expected to hit over 30 cities.
ImaginOcean, according to press notes, is a "one-of-a-kind, innovative glow-in-the-dark musical that opened in New York in March 2010. The 50 minute production features extraordinary puppets, memorable original songs, and a heartwarming journey of discovery by three loveable fish named Tank, Bubbles, and Dorsel who take the audience on their singing, bubbling, jiving adventure, making friends along the way."
