New characters will be coming to Disney Junior - Live on Stage! at Disney's Hollywood Studios and Disney California Adventure in 2013. Characters from the hit new Disney Channel shows "Doc McStuffins" and "Sofia the First" will join the show on February 15 in Florida and mid-March in California. "Little Einsteins" and "Handy Manny" will no longer be seen in the stage show, but the "Mickey Mouse Clubhouse" and "Jake and the Never Land Pirates" segments will remain. There are no planned character changes for the Play 'n' Dine meal at Hollywood & Vine.
