THE BACKYARDIGANS LIVE!
7 p.m., Robinson Center Music Hall. $17.50-$38.50.
Based on the popular Nickelodeon cartoon that you've probably only heard of if you're between the ages of 2 and 5 or if you're the parent of a child that age, “The Backyardigans” is all about kids using their “vivid” imaginations to come up with wild adventures in their backyard. The live-action performance at Robinson, subtitled “Tale of the Mighty Knights,” follows two backyard friends, Uniqua and Tyrone, who become knights charged with protecting King Pablo's “unpredictable egg.” Look out, also, for descriptive-adjective-heavy Grabbing Goblin Austin and Flighty Fairy Tasha. Parents and children be warned, Uniqua and Tyrone won't protect the “unpredictable egg” or do whatever they're supposed to be doing without help from the audience, which very well may mean singing and dancing.
