Original Description:
 
Fairy Floss and Patty Cake, the twin little sisters of Rosary, and the little daughters of Pokey Pierce and Pinkie Pie.
 
Fairy is a loud and nosy little girl who learned to fly at a young age and uses this to zip around Ponyville and listen to Gossip and general news. She’s optimistic and nice to everyone, and often can’t see the bad in others. She may or may not keep a secret candy stash under her pillow. Although she stubbornly denies it, she’s afraid of height, and typically stays a few feet from the ground when flying. She’s physically petite and is very quick, both on her hooves and her wings, and even has a tendency to talk too fast.
 
Patty is the opposite- she’s a clumsy little unicorn who has a tendency to let her mane fall in her face and tumble over nothing. She likes to be accompanied wherever she goes, usually by Gummy the alligator. She’s jumpy and self conscious, as well as pigeon toed, so she kind of waddles everywhere she goes. She can’t really run that well without problems, which is why she likes to be accompanied by someone. She liked being picked up occasionally, but doesn’t like it when her hooves can’t touch the ground.  
She’s the voice of reason in a lot of the pranks her and Fairy like to pull, and Fairy is her best friend right in front of Sugarcube.
