When Twilight Sparkle needs to see the dentist, some extra precautions are needed. The unicorn is not so very fond of doctors, so Spike has to resort to extreme measures, with some help from his friends.

"Once upon a time," said Fluttershy, "there were two sisters who lived with their mother in a cabin in the woods. They loved each other very much."

This story is a sequel to Teething Problems

Twilight Sparkle has been called to go on a business trip with the two princesses, and takes Spike along with her.

The trials and tribulations of inter-realm travel are not for the faint of heart, as they are about to find out.

Twilight is approached by Applejack with a strange request - to join her that night for a run, but all is not as it seems. Why is Applejack so nervous? What could this be about?

Rainbow Dash's latest flying routine was interrupted by a sudden mountain, and Twilight can hardly sleep at night. No pony should be this excited to play with necromancy.

Rarity's family name is in shambles, and her fortune is nonexistent. To return what her father squandered, she and her good friend Pinkie Pie turn to piracy, commandeering a magical airship and kidnapping the princess's personal student.

When Princess Celestia learns of Twilight and Applejack's abduction, she doesn't agree to pay the ransom. No, she hires the sky's greatest tactical mind, the Daring Swordspony Rainbow Dash, and her sidekick, Fluttershy. As the two groups engage in a game of cat and mouse, more dangerous threats hang on the horizon. Aztec Curses, angry gods, and a mysterious figure known only as the Derp Pirate Roberts.

Will the six Elements of Harmony be able to gather the seven pieces of eight, or will the world fall to utter chaos, and rise up as an empire of anarchy and piracy?

In the wake of the events of "Infernal Machines" and the Nightmare's most pathetic assault on Ponyville yet, Applejack is thrown into an existential crisis, despite her not knowing what the word "existential" means. So when a stranger named Stranger arrives in town, teaching a new way of coupling talent to power using complex machinery, she is quickly suckered in, along with everypony else. Now, it falls to the Most Dependable of Ponies to bring the resulting ruckus down to earth, but can even Applejack's legendary pragmatism stand up to the brain-fizzing horror that is... CONTRAPTIONOLOGY?

Now with a Spanish translation by Spaniard Kiwi!

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
