Following capacity crowds and raves from NYC to Hollywood, the interactive family comedy “Show Up, Kids!” makes its Brooklyn debut at The Rat NYC in DUMBO. This semi-improvised musical show for kids 3-10 years old puts a wildly comedic twist on the traditional kids’ show. When the main attraction doesn’t show up, the host enlists the help of the kids (and their grownups) to control everything from plot to props, characters to costumes, and settings to sound in a one-of-a-kind, 45-minute laughfest.
