The ever-expanding kiddie empire of Australian children's entertainers the Wiggles isn't all that surprising. After all, if there's one demographic that is easily cajoled into buying stuff, it would be the "younger than 10" crowd. Of course, Greg, Murray, Anthony, and Jeff can't be everywhere at once, so rather than leave kids waiting around for the next Wiggles concert tour, the foursome sends out its troupe of sidekicks. In its first appearance in the United States, the Dorothy the Dinosaur Show comes to the Coral Springs Center for the Arts (2855 Coral Springs Dr., Coral Springs) at 4 p.m. The show features Dorothy, of course, as well as Wags the Dog, Henry the Octopus, and the fearsome Captain Feathersword -- OK, so the Feathersword guy isn't really that fearsome. But along with the three animals, the captain stirs up all sorts of merriment for kids of all ages. Call 954-341-8300.
