(Slight spoilers for Chapter 5 of Make Your Mark. Takes place between "Mane Smelody" and "Nightmare on Mane Street".)
As a result of "The Mane Smelody Challenge", Mane Melody's reputation has taken a bit of a hit. A guilt ridden Pipp desperately searches for a way to restore it, and to hopefully redeem her own reputation in the process.
Eventually, Pipp learns that some of her youngest Pippsqueaks want to go on a field trip to Zephyr Heights, but they can't raise enough money for their school to hire chaperones. That gives Pipp an idea: She'll host a charity livestream at Mane Melody.
Rocky and Jazz are a bit hesitant to endorse another one of Pipp's ideas so soon after her last one failed. Can Pipp convince them, and by extension everypony else, that her social media influence can be a force for good?
