It is a slow day at the boutique, and Rarity has been quite productive out of the blue. However, after some sibling interactions, things become much more playful between her and her sister. Soon, the two are getting together in a way sisters normally would not. And soon after that, some very strange things start going on between the two. Opal and Tank, who Rarity is pet-sitting, aren't free of oddities either. None of them are going to end the day quite the way they started it.
