Today's… er, yesterday's prompt was Draw a pony celebrating your favorite holiday / Draw a pony partying too hard. Something strange occurs deeper in the pyramid… the temperature starts dropping dramatically, at an unusual rate even for an underground enclosure, and snow and ice starts to form everywhere! Clearly, there is only one logical reaction… celebrate Winter Wrap-Up in the middle of August! …Or maybe Derpy and Lyra should stop their partying and actually focus on the situation at hoof.

To prevent cheating (I'm sure no one else cares if I do or not, but I care), I have not looked at the next prompt in the ATG at the time I am writing this. I will see what it is once I finish this submission.
