One Bad Apple is the fourth Season 3 episode of My Little Pony: Friendship is Magic.

This episode last aired on Discovery Family on December 26, 2021 at 7:30 a.m., during the final marathon.


Apple Bloom's cousin and fellow "blank flank" is coming for a visit and the Cutie Mark Crusaders can't wait for her to join their club. But their hopes of gaining a new member are dashed when it turns out that all she wants to do is bully them.


Before this episode started development, several canceled ones were also planned. On June 21, 2011, Meghan McCarthy wrote a premise for an episode titled "Little White Lies", where Applejack tells a white lie to help out Apple Bloom, who is still being picked on at school by Diamond Tiara. A week later, on June 28, the episode was re-titled "Pony Little Liars", before it was replaced by a completely new story titled "Bully for You" on July 12.

Cindy Morrow wrote the full outline from July 15 through August 4, 2011, then the first full script from August 8 through September 12. Revisions were made to the script from September 15–22. After the final draft was done, Bully for You was re-titled "One Bad Apple". Voice recording began on November 3, after the song "Babs Seed" was first composed and performed on October 12. The song was mixed on November 18.

The full animatic was submitted for review on February 21, 2012.

A rough cut of the animated episode was submitted for review on June 26, 2012. A final version of Babs Seed was performed and composed on July 13, 2012.

Production was officially complete on August 21, 2012.
