Flutter Brutter

Flutter Brutter is the eleventh episode of season six of My Little Pony Friendship is Magic and the one hundred and twenty-eighth overall.

Production
When asked on Twitter about Fluttershy's parents in March 2015, Jim Miller replied, "If we had an awesome story for them, I wouldn't say it was out of the question." Fluttershy's brother was initially revealed by Andrea Libman at the 2015 San Diego Comic-Con International.

In production order, this is season six episode twelve.

This episode was to be included in the Shout! Factory DVD My Little Pony Friendship Is Magic: Friends And Family but was replaced with The Gift of the Maud Pie.

On March 13, 2016, Jim Miller implied the episode to be without Pop Fly.

Similarly with The Fault In Our Cutie Marks   and with Applejack's "Day" Off, IMDb credited David Godfrey as the voice of Mr. Shy in season six episode twelve,  referring either to this episode—months prior to the episode's scheduled premiere—if production order was used or to Spice Up Your Life if (scheduled) premiere order was used.

On April 27, 2016, Jim Miller was asked "Ouch, are we aiming at Bronies with the Flutter Brutter episode? Or just 4chan?" and replied "Neither. We don't follow that as much as you all seem to think."

From Discovery Family Channel
"When Fluttershy’s self-absorbed brother starts freeloading off their parents, she encourages him to move out. Unfortunately, he moves in with her instead, forcing Fluttershy to stand up to her brother and help him get over his fear of failure."

From Verizon FiOS and Zap2It
"When Fluttershy tries to convince her freeloading brother to move out of their parents' house, he moves in with her instead, forcing Fluttershy to stand up to him and help him get over his fear of failure."
