Grover, left, and Katie perform on stage during a live show at the base theater aboard Marine Corps Air Station Cherry Point, N.C., Sept. 10, 2016. Sesame Street and the United Service Organizations Inc. are addressing the challenges military children face from constantly moving to new duty stations through their popular show “Katie is moving to a New Base.” Katie is a character specially designed for military children to relate to. The show will run as part of the 2016 Sesame Street/USO Experience for Military Families, which is scheduled to perform more than 160 shows at 50 military bases in the U.S. through October.
