Perry snuck in through the vent, his heart beating violently inside his chest. He crawled on his hands and knees, brown eyes flickering to the side as he slid against the cold shiny metal that surrounded him. He moved his eyes forward as he turned a corner and approached a light that should lead him to the chosen room where his nemesis would be.

The platypus approached the vent screen and pressed his face against it, fighting to control his breathing. He squinted as he peered through it, listening intently for any sound of his nemesis scheming below him. But all that he found was complete silence in an empty room.

Still being as quiet as he could, Perry reached in to his fur and took out a screwdriver, twisting and turning it and pulling out the screws when they became loose enough. He pulled the vent screen inside with him, putting it on the side of the wall. Perry crawled forward to the edge of the drop and easily jumped out of the vent, grabbing on to a hanging light. He swung in the air for a few moments before dropping on to the couch far below him.

Well that was easy, he concluded. The platypus landed in a fighting pose, looking left to right for any signs of movement. Nothing. Not a sound or sign of Doofenshmirtz even being in the building. Perry looked around more, slowly starting to lose his defensive stance.

Too easy, he decided.

"Ah ha I've caught you Perry the Platypus!"

At the sound of the voice Perry instantly jumped to the side, dodging a trap that was falling down from the ceiling. It landed next to him with a clang and Perry faced the voice of his nemesis, fists closed and at the ready.

"Curse you Perry the Platypus you've never dodged my traps before so why now!" Perry's nemesis Heinz Doofenshmirtz walked out of the shadows, glaring venomously at the small mammal. Perry shrugged and kept his fists in a tight hold, all senses on alert.

Doofenshmirtz kept glaring at him before finally pressing a button that was on the wall near him. Perry jumped forward now to avoid being caught in this trap, but as he fell instead of rolling and hitting soft carpet, he fell in to deep clear water.

What?

Perry looked left and right as the tank he was in began rising up to Doof's level. Some scuba gear floated down for the platypus and he instantly took it, the brief panic that had been in him ceasing quickly.

"There see this time I was prepared," Doof smiled triumphantly as he watched his semi-acquatic nemesis pull on the scuba gear, but left the face mask. "Cuz last time I tried this it didn't really work out." Doof felt his face flush at the memory and he turned away, clearing his throat loudly, "Ahem. Anyway," now he spun back to face Perry, who rolled his eyes at him, "I haven't really finished my new inator yet so you'll have to give me a couple of minutes. You stay there Perry the Platypus and don't try to escape."

What no dramatic back story? No musical number? I'm dying over here Doof, Perry thought. If he was in a normal trap he could have just written this on a small notepad he used sometimes to get things straight with Doof. But seeing as he was under water, that probably wasn't going to work. Perry pounded his fist against the glass, but of course it didn't work.

"No noise Perry the Platypus!" Doof scolded as he walked away. "I don't want to hear any noise from you! You should be perfectly fine where you are! I even got you a few friends."

Perry looked over to see a few fish swim around him. He smirked and swam around the tank, searching for a way out. A trap door or something.

Meanwhile, Doof walked over to his computer and sat down in his spinny chair. He looked past his computer over at the platypus who was still swimming around in the tank, weaving through the seaweed and fish. Doof smirked. He didn't actually have any plans today, but it was nice to have the platypus for company, even if they couldn't talk to each other. Doof turned back to his computer game.

"Haha Perry the Platypus!" Perry heard about ten minutes later. His heart beat faster as he swam right at the glass, pressing his face to it to see Doof. The evil scientist laughed maniaclly. "I've won Perry the Platypus I've won! And there is nothing you can do to stop me!"

Dang it! And I don't even know what the plan is! How am I supposed to include this in today's report? Perry beat his fist against the glass uselessly. Maybe if he swam to it fast enough…

Doof looked over a few moments later when he heard a loud pounding noise. He moved his head over past his solitaire game to see his nemesis swimming recklessly at the glass. The tank shuddered but didn't break, not even a crack split up the sides.

Doof widened his eyes before glaring sternly. "Perry the Platypus you crazy don't do that it's dangerous!"

But Perry kept swimming at the glass, going to the far back and swimming as hard as he could, hitting his head against it. It hurt every time but he kept doing it. Doof narrowed his eyes slightly. Okay this was not going to be good. . .

"Perry the Platypus stop it!" he scolded loudly. "You're going to hurt yourself and use up all of your oxygen!"

After five more times the platypus felt himself tire out. His head throbbed painfully. Okay just one more time, he told himself. Just one more time and that'll be it.

The platypus swam to the end of the tank and went as fast as he could, putting as much strength in his muscles as he could. He looked over at his side to see all of the fish swimming alongside him. He widened his eyes for a moment and beat his tail faster as he collided with the glass wall.

There was a loud crack. Doof widened his eyes dramatically and jumped back as the glass tank shattered. Perry the Platypus and all of the first rocketed forward, the water pooling out and spreading through the entire apartment. Great now Doof would need some more money to hire someone to clean it all up. Maybe he could get Norm to do it. . .

"Perry the Platypus you've made me all wet!" Doof groaned. "And it's going to take me forever to clean this up how can you be so cold?"

Perry sat up, shaking his head and placing his hands on the side of it. Doof approached him and knelt down, looking at the platypus uncertainly. "Perry the Platypus did you hurt yourself?"

The platypus glared at his enemy. Refusing to show weakness he stood up shakily and got in another fighting stance. But as he stood his stance wobbled and he gave a weak chatter. Doof stood up to his full height and raised an eyebrow.

Perry suddenly caught sight of something red on his arm. His eyes flickered to it for a moment and his heart froze.

Blood.

The smell of it hung in the air and Perry felt his head grow light. With one more look at the oozing red on his arm the platypus felt himself pass out.
