Nothing suspicious going on here.
Just a group of bugs coming together to create a show for everyone to watch.

Twilight doesn't believe it for a second.

Spicy food and stress might be a part of your daily life, but it's finally caught up with you. You're in pain, the doctors wont help, and you're completely out of options. Well, almost out of options. Applejack has this zebra she knows named Zecora who just might be willing to help. But her help isn't quite what you had in mind.

Warning: Contains vomit and Anon. You decide which is worse

There's a lot of unpleasant surprises that can be found in photo albums. A third pony in what you thought was a private moment, inexpertly applied bodypaint, or just evidence of that time that your mother dressed you up like a burrito.

Twilight Sparkle was expecting to come out of Family Night with a few fresh blushes on her cheeks. What she wasn't expecting was a mysterious pair of wings in her baby pictures.

Hopefully Celestia will have some answers.

Many thanks to Present Perfect for supplying the brilliant concept, and to Evehly for the beautiful artwork.

It's usually boring work, maintaining an Equestrian border crossing. Doubly so if you're stationed at the Badlands crossing, with no incoming and a general populace still too busy licking its wounds to try anything funny. But it pays well, so guards tend not to complain.

But then you get the occasional day where everything goes wrong. Where an errant changeling with an attitude and an extremely punchable face tries to waltz past the station with a cart full of contraband, and sticky gross contraband at that.

If the border guard can get out of this one with all of their brain cells, they're definitely applying for a transfer to Ponyville.

Written as a birthday present for Carapace

There is a hidden village deep within the untamed forest surrounding Neighagara Falls. Should one ever journey to this village, those who live there will welcome them for a simple price: love.

When the village accepts a new family from Cloudsdale, a not-quite-altruistic pair of changeling siblings offer a young filly friendship and a chance to find her place in the strange village she hopes to call home.

Because when her Pinkie Sense is going off and she just knows somepony's been denied the birthright which is their birthday celebration, she'll go anywhere and do anything to make it right. Even if anywhere means heading deep into a changeling hive, and anything is... well, anything!

But she'll do whatever it takes.

Birthdays are important.

Cadance didn't know what to expect when her formerly banished Aunt Luna returned from her thousand year banishment. But, she's quite entertained by the hilarity. Especially if it means a chance to play a little joke.

Now with Spanish translation by SPANIARD KIWI.

The changelings have been plotting their revenge ever since the wedding, to little avail. Most of their sleeper agents have been rooted out, there are regular guard patrols along the borders of the Badlands, and every deal they've made has been betrayed in record time. The only changelings not starving to death are the ones who have sold off the queen's secrets for clemency.

But despite all of these setbacks, Queen Chrysalis has a plan. A plan that, if she pulls it off, could topple the Crystal Empire in one fell swoop. Of course, it has more than its fair share of risks, but the reward will make it all worth it.

Rated Teen for brief descriptions of the various mechanisms of birth.

Also, don't worry about spoiler tags. The premise of this piece should seem fairly obvious.
