A/N The prank cave is borrowed from explodingskies. It wasn't my idea.

Andi rushed out the door and headed for the Prank Cave. She pulled down on the tree branch and opened the door. Travis had also followed her, to get alarm clocks for him and Hermes. They went down the corridor with the help of Travis's flashlight. once in the cave, Travis opened a chest of alarm clocks- a weird thing to have, but great for keeping your enemy up all night. He filled a bag with ten or so and left again. Andi turned her attention to the prank cabinet. She wondered what flavor of toothpaste to take. They had four awful flavors of toothpaste disguised as regular camp brand. She scanned the rows. They had Jalapeno, Salt, Pepper, and Salmon. She grabbed one of each and headed back into the daylight.

Andi squinted in the glare of the sun, but even from here, she could see that Athena was having Archery and Percy was canoeing. Technically, she should be at javelin trowing, but oh well.

She started with the Poseidon cabin, since Percy looked like he could be coming in at any time. She snuck through the front door, and kept her eyes peeled for any traps he might have set, but there were none. She smiled. He was getting cabin was pretty basic, just a large room really with an attached bathroom. The Hermes cabin had all sorts of hideouts, secret rooms, and even underground tunnels and rooms. She guessed that Percy didn't need to hide as often as children of Hermes did. She made her way to the seemed he had just gotton a new tube of toothpaste, since it was almost full. She selected the Salt flavored one and carefully squeezed a bit out into a bag. Now it was almost the same size as his old one. She smiled and took his, leaving the salt one. Andi reemerged into the daylight and sighed. One down, four to go.

She glanced over, seeing the Athena kids still at archery. Still, she ifgured it would be best to take the secret door into their cabin. She headed back to the prank cave and looked at the maps. Over the years, children of Hermes had created secret doorways into all the cabins and the Big House. Currently, they were trying to make doors into the new cabins being built, and it was going good. They had doors into Nike, Hecate, and Iris so far, and they had been working on getting one into Hades. She noted the tunnel she needed to take tp get into Athena and headed into the vast tunnel system. She knew she was getting close when she heard cursing. She silently opened the door to see her dad struggling to wind up an alarm clock, even with Travis's help. They seemed to be having so much trouble setting them that they hadn't noticed her approach.

"Problems?" she asked smoothly. They both jumped and wheeled around. Travis had attempted to draw his sword, but he saw it was only her, laughing in the doorway.

"If it looks so easy to you, you try it." He said.

"Alright, give me one." Hermes gratefully handed her the one that he'd been grappling with. She took it from him and easily set it for midnight. They stared at her, dumbfounded.

"How'd you do that?" Her dad asked, curious.

"You wind it until it reaches the time you want, like so." She took another clock from the pile and rigged it for one am. "Think you can handle it now?"

"Of course we can. Just needed a little reminder." Travis tried to lie his way out. Andi just rolled her eyes at him and walked to the bathroom.

The counter top hand two sinks and seven cups, each with a different name printed on it in in all caps. They each even had a different color cup. Still, four of Annabeth's siblings hadn't been involved. She read : ANNABETH, MALCOLM, TIMOTHY, DENIS, SALLY, LIAM, RICK. She carefully removed the tubes of toothpaste from Annabeth's Malcolm's and Denis's cups. She took the salmon out and pressed about half of it into a bag to be reused later, the put the tube in Denis's cup. She did the same with the pepper for Malcolm and the Jalapeno for Annabeth. She took a step back and smiled. They would never want to brush her teeth again.

Travis and Hermes, meanwhile, had finally managed to set the alarm clocks, each n hour apart, starting at midnight and ending at seven. They were now in the process of hiding them around the dorm room. Travis reached to hide one under Annabeth's bed as Hermes put one in the closet. These things were ridiculously loud, and impossible to sleep through. They would be having a rough night.

Hermes shut the closet door. "Ready to do the Poseidon Cabin?"

"Absolutely. Lets go. They passed Evelyn as they headed back to the secret passage. She was currently wrapping the doorway into the bathroom with a thin layer of Saran Wrap. She was good, not a single wrinkle. You could barely tell it was there.

Evelyn looked up. "I thought Travis was doing this cabin and Dad was doing Poseidon."

"It takes two of them to set an alarm clock." Andi told her from where she was leaning on the doorframe.

Travis started "We were just helping each other out, and…"

Evelyn cut him off. "Just go! It's already 1:15!"

"K. we're going. See you later." Hermes said as he pushed Travis down the hall to the secret tunnel. They jogged down the path in silence. Finally, Travis broke into it. "We kinda did fail at setting those clocks…."

Connor, meanwhile, had just found another fountain in Poseidon's cabin.

He had already found three, and each one took time to color. He had the put in coloring, stir as best he could, then wait for the pump to circulate a few times to make sure that the color was good enough. As he did the same with the fourth, he admired his work in the others. He had debated choosing blood red or fire engine red, but he was happy with his choice. Percy's fountains did indeed look as though they were filled with blood. Now, if the last one would just hurry up…

Suddenly, he heard something bad outside. The fountain had just finished and looked perfect when he heard the dreaded noise. Someone was on the front porch. And he was coming inside. Connor didn't even have time to run. He lept behind a fountain just as Percy entered. He was obviously deep in thought, because he didn't even notice his fountains. He just grabbed something off his bunk bed and walked right back out. Connor watched him, as he walked away, back towards the lake, and breathed a sigh of relief. As soon as Percy was out of sight, Connor left the cabin and walked back towards Cabin 11. He'd had enough of the Poseidon Cabin for now.

Chris was delighted when Connor entered. He'd been done with his part quickly, and had been slowly going out of his mind from waiting. The clock read 1:25. The others would be arriving soon. Almost as if by magic, Andi and Evelyn burst through the door, grinning like mad women. Their parts must have gone well. Everybody looks at the clock. Now it's 1:27, and no sign of Travis or Hermes. They glanced nervously at each other. Their leader and dad were cutting it awfully close.

1:27 turned into 1:28. They couldn't really do anything without the head of the Revenge Department, so they just waited.

1:28 turned into 1:29. Just then, they heard footsteps on the porch. Travis and Hermes walked in, huge smiles on their faces. Glancing around the cabin, everybody else was smiling, too. Part one of the plan was done. Now just waiting for their victims reactions.
