In 2013, Kathryn Mullen attended Dragon Con with Karen Prell and Michael K. Frith as part of the 30th Anniversary of Fraggle Rock where Kathryn Mullen performed Mokey Fraggle while Karen Prell performed Red Fraggle.
Kathy Mullen, with her husband, former Muppet designer Michael K. Frith, founded "No Strings" along with emergency aid worker Johnie McGlade. The company originally created a film for children in Afghanistan, warning of the dangers of land mines. In the film, "The Story of the Little Carpet Boy," one puppet loses several limbs before he learns to avoid land mines completely. Since the first film, No Strings has gone on to create films for children in need in areas including Africa, Haiti, Madagascar, Sudan, and Syria. In 2016 No Strings was awarded the 2016 Adela Dwyer-St. Thomas of Villanova Peace Award from Villanova University
