How Derpy Got her Cutie Mark and Learned to Love the Bubbles
My alternative headcanon for Derpy - perhaps she's not "a few sandwiches short of a picnic" like we all thought! There's not much actual fear in the story. And no loathing at all. Misleading title — sorry.
WARNING: Muffins!
This was written as flash fiction. Flash fiction is traditionally under 1000 words, but this site places a 1000 word minimum length on stories, so I've also included an epilogue, which fills out Derpy's story even more. (The epilogue can be seen as an optional extra - each chapter can be read as standalone story.)
The cover image uses this picture of filly Derpy and this muffin. Much thanks to all those people who create such beautiful pony art and give others the freedom to remix it. You are gems!
That was fun!
I didn't take the time to over analyze your writing style, but I can say nothing glaring jumped out at me. So, a big thumbs up!
Aww, that was really cute! I fully accept your headcanon for how Derpy's eyes came to be, that is certainly an unusual (but useful!) talent she has there
The epilogue with Pinkie was adorable too, I can totally see her doing that and I liked your characterization of Derpy in general, how sweet and eager to please she is. Nice job! 
That was a nice, cute, and fun little short story! I loved it! It's so nice to see Derpy getting her cutie mark and interacting with the other pegasi in Ponyville.
The only typo I found in the fanfic was this part in the epilogue:
It should be "pegasi". Other than that, I found no other errors. Once again, great job on your first story on Fimfiction!

Thanks for the comment. Although this is my first story here, it won't be my last. The next one is just taking a while (it's somewhat longer).
Apparently both "pegasuses" and "pegasi" are acceptable plurals of "pegasus", but I used "pegasi" elsewhere in the story, so at least I should be consistent! Fixed now.
Interesting take on Derpy's origins.

I knew it. Derpy is part chameleon.
Simple and short. I enjoyed it well enough. Interesting idea for how she got her talent and learned to multitask.
Awwwwwwwwwwwwwwww
I love it! Totally new headcanon!

What did her cutie mark mean?

Do they represent that Derpy has more than one brain?
