PERILOUS PINK: Think of it as a cautionary tale for the tutu-wearing set. “Pinkalicious, the Musical” tells the story of a little girl who develops a full-body blush after bingeing on pink-frosted cupcakes – and that makes her feel pretty blue. Based on the book “Pinkalicious” by Elizabeth Kann and Victoria Kann, with music by John Gregor. So if you are in, or wish to head to NYC call for reservations: (212) 352-3101. Saturdays and Sundays through Feb. 25 at 11 a.m. and 1 p.m.; $18. Vital Theatre Company, 2162 Broadway (fourth floor), at 76th Street.
