A Change' in Appetite

I trotted towards my cottage. It was such a great day! No dragons, no curses, no mean griffins, no nothing! I mean... well.. um I wasn't one of the Mane six but yeah that stuff happens in Ponyville a lot!

I was about to open the door when I noticed the mailbox flag was up. I opened it and sure enough there was a letter and a bottle. This was no ordinary letter though (well for me it wasn't), it was from Princesses Twilight! I jumped with joy! But as soon as a read the letter I didn't want to to jump anymore.

Dear Moonlight Gambit,

I would like you to test this potion I have made. It's a little project of mine It's suppose to make those who are sick feel the need to eat because well you know when ponies are sick they tend not to eat. I need to test it on a Earth pony like you because I'm seeing that some pony types have a different reaction to the potion. I was originally going to test it on Pinkie Pie or Applejack test it but they are away because Pinkie wanted to know if she was part of the Apple family.  Well anyways let me know what happens.

Sincerely,

Twilight Sparkle

Me? Are they kidding?! A scaredy pony like me test a unstable potion. Nah uh!
