Luna teleports Celestia, Cadence, Shining Armour, Flurry Heart, Rainbow Dash and the guard Thunderhoof and herself to Manehattan, where they see ponies running around screaming.
"Oh no!" Rainbow hid behind Celestia. "It's too late. There are zombies here too!"
"Rainbow Dash, please calm yourself." Celestia tells the pegasus.

Rainbow screamed when a zombie came close, however Cadence put a magic bubble around them.
"There." She said. "No zombies can touch us." Suddenly Thunderhoof screamed, pointing a hoof at Shining Armour and Flurry Heart.

Both zombies.

Rainbow again screams, flying up, out of the magic bubble, and up. Up as far as she could go.

Thunderhoof ran. Ran as fast as his hooves would take him, thundering on the hard concrete.

Cadence's bubble fades away, and the three princesses fly out of reach of the two newly formed zombies.
"I didn't even see one touch him!" Cadence cried, staring at her husband and daughter.
"We need to get away from here." Luna exclaims.
"Where would we go?" Rainbow shouts from up high. "Everywhere we've been there are zombies!"

The four non-zombies look around, noticing in utter shock that everypony they could see in Manehattan had turned into zombies.
"We're doomed!" Rainbow cried. "Nowhere is safe!"

The sound of loud hooves quickly approached, and the ponies saw Thunderhoof running towards them.
"This way!" He shouts, before leading the princesses and Rainbow Dash towards the train station.

Everypony at the train station was fully pony and fully terrified. Eyes turned towards the five ponies as they approached, backing away in fear.
"Do not worry, everypony." Luna told them.
"We will find a place that is zombie-free!" Cadence added.
"We will swear this!" Celestia added.

The Friendship Express arrived at the station, and ponies clambered on.
"Where are we going?" An earth pony known as Coco Pommel asked the conductor as he stared at all the frightened ponies.
"Uh," He looked towards Coco, before the princesses, and the others. "We actually have no scheduled stops currently," The conductor said, before Rainbow flew up to his face in fear.
"Please, just take us somewhere!" She cried. "Anywhere that isn't infested with zombies!" The conductor put his hoof to his chin.
"Everypony, please take a seat." He announced. "We're going to try our luck at Appleoosa."
