The Fishy Aquarium

"Yohoooo!" squealed Clarisse as she cascaded down the water pipe. Sarah's terrified screams echoed behind her. A few seconds later, they flew into the daylight and then immediately crashed into the water pool below. They emerged from the water- Clarisse giggling, Sarah coughing.

Sarah eyed the water slide warily. The thing spouted a person every few seconds- who fell into the water with euphoric whoops. Sarah had been anything but euphoric. Her feet and hands still trembled. Gravity coupled with a near frictionless surface was enough to accelerate you to heart stopping velocities. "A few seconds more," thought Sarah, "and my stomach would have been ripped off". Suddenly, Clarisse caught her arm and spun her around- so that they faced each other. She scooped up some water and splashed it in Sarah's indignant face. They both fell back choking- Clarisse from laughter, Sarah from water. A friendly fistfight ensued as each sister vied for dominance.

"Ahem," coughed Percy, surprising Clarisse, and Sarah wriggled out of Clarisse's bear-like cluthes. They grinned at Percy who just sighed. "Let's not try to kill each other before lunch. What'd you say about a visit to the Aquarium of Death?" They rolled their eyes at the histrionic name, but agreed. Shaking their heads, they joined the long ticket counter.

They were soon joined by Annabeth; Percy welcomed her by wrapping a loving arm around her waist. The sisters smirked at each other. "Percy," asked Sarah, "how long do we wait in this line?" "Dunno, could be minutes or hours." Thankfully, they were soon before the ticket counter manned by a bright- eyed woman. "Four tickets for the aquarium please," requested Annabeth, as she passed the money over. The woman narrowed her eyes, "But there's only two of you". Percy quickly turned around where Sarah and Clarisse ought to be, only to find them missing. Bewildered, he scanned around, "Oh there they are," relief obvious in his voice. He called them over.

"And who are these ladies, may I ask?" The woman eyed them skeptically.

"They are..." Percy smiled as he lay a hand each on Sarah and Clarrise's shoulder.

"They are my daughters."

The aquarium guide pointed at the strange fish and said, "This one right here, dear ma'am, is called Pentaden Buchholzi. Inexplicably, people prefer to call him Jim". Annabeth smiled and the guide opened his mouth to resume. Percy interrupted him.

"Pantodon not Pentaden"

"S'cuse me?"

"It's a Pantodon, not Pentaden. And his name's Dominic, not Jim."

The guide narrowed his eyes and then cleared his throat. "Umm… yeah. As I was saying, these tough suckers inhabit temperate waters during the…"

Bored, Clarisse and Sarah wandered off. Annabeth noticed but didn't object. After strolling aimlessly for a few minutes, they entered a dimly lit exhibit. It was obviously under maintenance; the aquariums were empty and the floor was slippery with water. In the corner sat a neglected aquarium, with a seahorse too large for it, swimming around desolately. Fish flakes and pellets floated about in the dirty and murky yellow water.

The sisters approached carefully and touched the glass; the seahorse glared at them. "Hi, little Diana!" giggled Sarah, oblivious to the spite in it's face. However, Clarisse noticed, "Those eyes creep me out. It looks… angry". Inadvertently, she banged the glass, fully expecting the seahorse to jerk back.

Instead, it was them who fell back. The creature uttered a low growl and it's little flippers warped into arms, about half as large as a human's. It drew back it's arms and struck a powerful blow to the glass, causing it to shatter. Fish and yellow watered tumbled down with a splat and whoosh. Before the sisters could react, the seahorse was upon them, using it's now transformed leg/tail. It pinned down Sarah with surprising agility for a dumb watery creature. It's long snout shortened into a ferocious mouth full of pointy, poky teeth.

"Sarah, use your bracelets! I will distract it, go!" Clarisse yelled as she picked up a metal rod from the ground. She yelled defiantly and charged at the creature, swinging her rod as a baseballer would. The monster bounced away, snarling. Brave as Clarisse was, she was reckless too.

Sarah could only watch in horror as the fighters reared up to charge at each other. What bracelet had Clarisse yelled about? A memory tugged at her mind. Suddenly, she remembered a soft smile beaming at her from under a pair of sparkly sea green eyes. The cold metal against her hand grew warmer. Of course, Poseidon's gift! She touched the two bracelets on each arm together and a pair of wickedly handsome twin swords appeared in her hands, ready to slice and dice.

Clarisse was fighting a losing battle. The seahorse was beating her up mercilessly; blood ran down her cracked lips and nose. The sight of it got Sarah to work. She charged.

Clarisse noticed and somehow pinned the monster to the ground. A second later, the tip of Sarah's sword appeared before her eyes.

Sarah cried ruthlessly and plunged the sword between the monster's eyes. It howled and struggled but finally disappeared in a puddle of nasty-smelling water. Trembling, she pulled up Clarisse, who knelt against her shoulder.

A few minutes later, Percy ran into the room. He saw Clarisse and Sarah sitting against a box, beaten up but very much alive. "What the-?"

Annabeth strode inside, her stormy eyes full of worry. As she scrutinized the room, her eyes softened.

"Shhhh… Percy. It was just a Naiad. They killed their first monster."
