In 'Derpy and Twilight Get it Together', Twilight is alone at night and needs somepony to keep her busy, so Derpy decides to help.
Then, in 'Rarity Teaches Sweetie Belle a New Skill', the fashionista helps Sweetie Belle to try and get her cutie mark with a rather dirty job.
And finally, in 'Snips, Snails and Spike Get Ready for Action", the story comes to a close as the unicorns prepare the dragon for a night filled with fun and excitement, then we see the night itself!
