Once in a blue moon...

"ACHOOoo!"

A thunderous sneeze could be heard around the castle. Celestia knew where it came from. As Celestia was walking through the corridors, some hitching breaths could be heard. She checked the clock. It was almost sunset, so she became slightly worried that this issue might not be resolved in time. Celetsia has not raised the moon for nearly one year, making her a little bit out of practice. She finally arrived at her sisters door. She could her her breath getting more desperate, close to release. Celestia knocks at the door a few times.

"eihhHCHOO!" - Luna sneezed

"Bless you, sister." - Celestia

"*SNIFF* Is it already time for the moon to set?" - Luna

"Do you think you can do it, or shall I raise the moon tonight?"  - Celestia

"I'm don't need help. I have been raisinging the moon for nearly a millennium." - Luna

"So have I." - Celestia

"Very well. You may come with me as I raise the moon." - Luna

The two sisters walk up a few flights of stairs. They reach the roof. Luna starts to raise the moon, while Celestia lowers the stats lowering the sun. The wind starts up. As it does this, it tickles Luna's nose.

"hiiee" - Luna hitches

"No Luna! You can't sneeze while raising the moon!" - Celestia, putting her wing under Luna's nose

*in ponyville*

"Spike, could you bring me the pepper shaker for my food?" - Twilight

"Sure!" - Spike

Spike can smell the pepper, causing an itch to form in his nostrils.

"ahh" - Spike

"Spike, be careful!" - Twilight

"ECHMPF" - Spike

The pepper made Spike sneeze, sending the lid flying off the pepper shaker, then sending the pepper container, full of pepper, to just above Celestia.

"Spike!" - Twiight

*back in canterlot*

A container full of pepper appeared over Celestia. The container hit her right on the nose, followed by a cloud of pepper surrounding her. She couldn't help but inhale some of the pepper.

"I th-hink I'm gonh-na... snehh... sneeze!" - Celestia

"No you won't!" - Luna

Luna extended her wing over to Celestia's nose. She covered it, in an attempt to stop the sneeze. The sun is now where it needs to be, and so  is the moon. Celestia looks up at the sun, and she just lets her sneezes out.

"IMPTCHOF!"

Celetsia sneezes, snot hitting Luna's wing. Luna pulls her wing away, tickling Celestia's nose as the feathers brushed past her. Celestia quickly pulls away too, which also does the same to Luna.

"MPTFFF!" - Celestia sneezes

"ECHOOOOO!" - Luna sneezes

"ECHAAOO!" - Luna and Celestia both sneeze at the same time

"cmpt! cmptoo! choo! chee!" - Luna sneezes uncharacteristically quietly.
