I always wanted to go to Equestria. When I got the chance, I took the deal without reading the fine print. To my surprise, I didn't arrive there as a pony, or even as a human. It seems I get to view this world from a different perspective than what I've imagined.

My name is Echo. I am a Diamond Dog.

Twilight Sparkle had been looking forward to a quiet, relaxing day with a friend, and at first it seemed that Fluttershy could provide just that. But when Twilight makes a rather unsettling discovery about the pegasus – and her unusually sanguine appetite – the knowledge proves to be anything but relaxing...

Twilight wakes up and finds out that she's changed back into a filly! What kind of trouble will she get into? How will her friends react?

Twilight Sparkle never was a Unicorn and she didn't even know it.
What happens when her true heritage comes to light? Will she willingly embrace it? Or will she be forced to?

Beware of spoilers in the comments!

It was true that the doctor had regenerated many times but this time something felt, different. He would think more on these things later because at the moment the TARDIS was crashing with more force than it ever had before. Plowing though dimension after dimension it finally decided to land in the backyard of what appeared to be a regular home. Thinking now was a good time to figure out why this regeneration had felt so weird. He walked up to his mirror and right of the bat he noticed why it had felt so weird this time. The three most obvious things that were new were these:one, he was a pony; two, he still wan't ginger; and number three, he was a she.

Everyone is familiar with the "waking up as a pony" trope, but no one expected this particular trope to occur in reality. Especially the 'pony' in this picture, who life gets more complicated then before. It will be a cumulative effort to adjust to this lifestyle, but surmounting this transformation is the only beneficial option.This story varies from mundane to supernatural carnage.

In hopes of breaking her normal routine, Twilight decides to make an effort to get away from her books and spend as much time with her friends as possible, dedicating one whole day to each of them.

Though nothing is as it seems. While spending a day with Bubble Berry, she receives a letter from Princess Celestia informing her that something sinister and magical is afoot in Ponyville, causing that day to be repeated. But with Bubble Berry asking her out on a date that very same day, Twilight may not have time to find the source of the anomaly while she comes to terms with the feelings developing between herself and one of her closest friends.
