The six pearl bearers were escorted to a giant underwater submarine. While they all had the same amount of magic, they were smarter than ponies and had invented machines made of metal like submarines. They would have used tanks and planes, but they had to stay underwater. It was said that the princesses had not thought up anything like this, but had the power to make such things if they wanted to.
The six boarded the submarine. Fluttershy looked up at the tallest tower of the castle and could barely make out Dinky Doo waving. She watched as Big Mac was lead onto their sub, becoming one of the royal guards of the pearl bearers.
They all watched as ten other subs were filled to the brim with soldiers. Finally, King Oceania boarded Fluttershy's sub. Smaller, faster subs surrounded each of the eleven subs as defense.
Then they started to move. They soon were gliding quickly across the ocean floor. All the windows were open so they wouldn't run out of fresh water to breathe in through their gills.
Fluttershy stuck her head out the window. A pod of fifteen blue whales pulled the sub from the front. The same was true for the other subs.
The time passed slowly as the hippocampi stood cramped in the submarine, pushed up against each other. If they were not underwater, they would all be sweating.
After an hour that seemed to take an eternity, the nervous sea ponies arrived at the shore of Equestria, home of the princesses. On land a giant army of Equestrians was waiting for them. Fluttershy could see Twilight's brother at the head of one of the groups of soldiers, giving orders.
Fluttershy closed the window in front of her as other sea ponies around her did the same. Quickly after, weapons and beams of magic hit the subs, who were half beached. The blue whales had been freed and had swam away. Wheels popped out of the subs and they began to roll onto the beach while the Equestrians.
Fluttershy could faintly see two large figures flying around a chariot that had the element bearers in it. Fluttershy counted six ponies in the chariot. Fluttershy opened her eyes wide and pointed it out to the other pearl bearers. Had they replaced her that quickly?
Meanwhile, some soldiers swam onto small spots on the floor. The spots rose up, encasing them and some water so the hippocampus inside could breathe. Then they were raised through the roof of the sub where they could fire freely with their magic at the Equestrians. Fluttershy started to shake as she watched Equestrian soldiers fall to the ground while all their attacks bounced harmlessly of the subs. Meanwhile the chariot and the figures around it got closer.
After a minute, the two ponies got in magical range of the subs and began firing. With their enhanced magic, the princesses broke some of the small pods on top of the subs, the pods exploding in a blast of bright light. Their pods began firing at the princesses. who easily evaded the attacks by putting up a strong magic shield around themselves and the chariot.
Meanwhile King Oceania swam over to the six pearl bearers while a giant pod burst from the wall engulfing him and the six.
He said to them" It is time," and the pod detached itself from the sub, propellers sprouting from the top of the machine. Then the pod whirred away towards the chariot, all the sea ponies inside except Fluttershy, who didn't have spines, building a shield in front of the pod.
