Ok, so I LOVE MLP and all things relating to it, and my fave character is Derpy. So I thought, why can't Derpy have a little sister? Will most likely be a one shot, unless I get a ton of good reviews! So enjoy!
"Derpy!" Pinkie Pie called out.
"Derps a Lot? Where are you?" Rainbow Dash asked.
Finally, Derpy emerged from her home.
"Oh hi guys, I just got lost in my room. What's up?" Derpy asked while eating a muffin.
"Uh Derpy, you never told me you had a little sis!" Rainbow Dash said.
"Oh yeah. I forgot about her. Where is she? Is she all grown up?"
"Uh no, she's still little." Applejack told her.
"Oh. Can I see her?"
"Sure!"
Out bounded a little pony, about the size of Sweetiebelle.
"Hiya Sissy!" said the little pony, Derpella.
"Oh hiya Derpella! Wanna come with me to an all you can eat muffin buffet?" Derpy asked.
"Sure!" said the little pony, and the two trotted off into the sunset, while the trio of other ponies shook their heads and trotted towards their homes.
