Water. That was the only thing little Luna could see in every direction. Stretching endlessly in every direction, spreading out beyond the horizon. Waves and waves of murky blue water. Salted, of course, as any ocean would be. Luna sat in a cardboard box which was jostled by the waves, bouncing calmly up and down with every swell and every crest. Although the box should have long ago become soaked and deteriorated, the waves did not harm it.
Luna was hungry. Thirsty. Tired. She'd been floating aimlessly for days, with no way to steer her craft, nor any control over what direction it was taken.
Gazing down beneath the waves, she could see the glittering scales of various fish that swam past, completely blissfully ignorant of her presence. She'd had fish before at several of the formal palace dinners, but as her stomach rumbled, Luna was left in a position of conflict. Mother had always told her not to harm another living thing, but that rule may stand between herself and starvation.
One would have to be enough. She'd punish herself later. Drawing breath, Luna leaned carefully over the side of the box and plunged her hooves into the water, trying to get a hold of one of the many small creatures that swam by underneath. Despite multiple attempts, every single one of them eluded her. She couldn't even manage to touch one.
Perhaps grabbing was not the way to go. She'd try impalement instead. Leaning over, Luna attempted to plunge her horn into the water, but her horn was too short and her body too small. After a couple of attempts, her center of gravity shifted and the young filly tumbled out of the box.
Flailing, Luna grabbed at the box. She prepared to pull herself back up over the edge, but some sort of restraint took hold of her back legs. Struggling and pulling, Luna tried to escape, but the restraints were too powerful. She was pulled underneath the waves, the only sign of her existence being a floating box and a few bubbles at the surface.
Underwater, Luna squirmed to get a look at her attacker. She could only see a pair of green tentacles ensnaring her legs, reaching up from the pitch blackness that hid the ocean floor somewhere far below. The tentacles tightened around her legs, pulling her downwards, towards certain death. She'd never-
"What are you doing?"
Celestia stood framed in the doorway that led to the west wing hallway, staring into one of the many guest rooms available in Canterlot Castle. A single cardboard box sat empty upon the expansive blue carpet, nearby which Luna was lying on the floor, with Discord clinging in a vice grip to her back legs.
"S'not what it looks like!" Luna protested. "And you can't be in here, you's standin' in the middle of the ocean!"
"Well, maybe that's my special power. I can walk on oceans."
"Nuh uh!" Luna protested. "You gotta be a narwhal!"
"A what?" Celestia asked, dismayed that Luna knew something she didn't.
"A big whale with a horn on it!"
Celestia looked shocked. "Did you just call me fat?!"
"Did not."
Running out of the room, Celestia soon had tears running down her face. "MOOOOOOOOM! LUNA CALLED ME FAT!"
Discord and Luna looked at each other.
"She just doesn't understand the complexity of the mechanics of our inner mentalities," Discord said.
Luna stared blankly at him. "What?"
Discord patted her head. "Never mind, you going to escape or what?"
"I's gonna use my magic!" Luna announced.
"You can't use magic, you're underwater," Discord said.
"Since when?"
"Since now."
"That's dumb, how do seaponies use magic then?"
"Uh..."
"That's what I thought." Luna stuck her tongue out at him.
Back underwater, Luna's horn glowed a bright pure white. The light that blasted from it was not a physical attack, but a blinding light that stunned her attacker just long enough for the tentacles to break free. Desperately swimming upward, Luna's head broke the surface and she gasped for air. Searching the ocean nearby, it took only a moment to locate her box and climb back into it. Luna took a moment to compose herself, then looked out over the edge of the box again.
Water. That was the only thing little Luna could see in every direction. Stretching endlessly in every direction, spreading out beyond the horizon. Waves and waves of murky blue water. Salted, of course, as any ocean would be.
