Dear Princess Celestia

I know it's been awhile since we last spoke and I'm sure Canterlot has been very busy ever since Tirek escape and his defeat, but I think something is very wrong here in Ponyville, do you know about the Miss Fortune make up line that was released Saturday? Because everypony in Ponyville has been acting very bizarrely ever since they've started using that make up, I've noticed it in almost everypony who's used it including Spike! And he only used it to try and cover up some suddenly discoloured scales on his face!
I've noted down some of the weird symptoms and behavioural changes I've been able to notice in other ponies whenever they've come into contact with other ponies:

1. Intense aggression
2. Sudden mood swings
3. Unusual amounts of wetness in the eyes
4. Rapid saliva production
5. Increased temperature
6. Fur/Scale loss

Spike was the first creature that I noticed began to rapidly lose scales after I found some of his discoloured scales discarded in the bathroom, I was hoping you'd be able to help so I'm sending them to you in this scroll, try to be careful with them as to avoid contamination.
I am aware that I probably sound very overly frightened about something that could just be an outbreak of some sickness but I fear this is somehow connected with that Miss Fortune make up line, please write back to me when you get chance.

Author's Note

I was hoping this story would be better written, I suspected that something more akin to less story and more mystery would be better
