Original Description:
 
Nightmare Night isn’t usually Fluttershy’s cup of tea..  
But it’s hard to say no to Rarity, and even harder to resist her magic as she slips on a thick diaper and a pacifier muzzle, oh no~!  
The muzzle is locked up tight behind Fluttershy’s head, and it’s not coming off until Fluttershy crinkly waddles around Ponyville, collecting candy and chocolate~!
 
My little really loves this idea, and made the most adooorable little muffled squeaks as we roleplayed it out - especially when Fluttershy had to go to Sugarcube Corner to say hello to Pinkie Pie%! It really loves to put its little hooves up and plead, being seen by every pony.. Its big poofy butt there for all to see, and for Mommy to check whenever she pleases%! This piece is mostly for it. I love you, my little one.~ Don’t worry, I’ll make sure all your candy is safe.~
 
I could have taken more time with this, fixed up some mistakes ( eyelashes arent perfect, the muzzle strap isnt perfect on the right frame), but I just wanted to make this comfy and cute for my little Fluttershy.
