"Filli Vanilli" is the fourteenth episode of the fourth season of animated television series My Little Pony: Friendship Is Magic, as well as the seventy-ninth overall.

Written by Amy Keating Rogers, directed by Jayson Thiessen, and co-directed by Jim Miller, the episode centers around Fluttershy secretly standing-in for Big McIntosh in a few concerts.

Big Mac lip-syncs on stage to hide it, but they are caught when Fluttershy accidentally knocks the curtain down.

Aired on February 15, 2014, on The Hub, the episode was viewed by 584,000 people and received praise from critics for its writing and overall message.

However, Big McIntosh, a member of the group who is supposed to sing bass at the concert, lost his voice during a turkey call competition.

Her friends find her at her cottage and convince her that facing her worst fear was not as bad as she had imagined because the audience loved her performance.

She added that initial name of the episode was "The Return of Flutterguy", which was changed to "Flutterfear" because the previous title gave "too much information."
