(Based on the YouTube video "Rarity Catches a Cold" by Magpiepony.)
Rarity is trying to finish an important order for a client, a task made very difficult by the fact that she has recently started to feel unwell. But she is determined to finish the order before stopping to rest.
It's ultimately a losing battle, Rarity finds herself so sick that she can't concentrate and decides to rest rather than spread her germs to the dress. Little does she realize or even suspect that her sudden sickness has other effects.
Traces of magic have seeped out from Rarity's horn, causing various items in the fashionista's workshop to come to life. Can a magically brought to life workshop finish a dress all by itself?
