In December 2011, Disney Channel pulled episodes of two of its original series from the network's broadcast cycle – the season one "Shake It Up" episode "Party It Up," and the "So Random!" episode "Colbie Caillat" – after Demi Lovato (star of "So Random!" parent series "Sonny with a Chance", who was treated for bulimia nervosa in 2010) objected on Twitter to jokes featured in both episodes (the "Shake It Up" episode, in particular) that made light of eating disorders. On May 17, 2013, the channel pulled "Quitting Cold Koala", a second-season episode of "Jessie", prior to its scheduled premiere broadcast, due to parental concerns over a scene in which a character's gluten-free diet leads to him being ridiculed.
