Disclaimer: I am not the owner of Phineas and Ferb or Rise of the Guardians, I've only borrowed the characters for this story!

Alright, this story is probably going to be only a few chapters long, but it was an idea I got stuck in my head and had to write down. I hope you enjoy!

It was a normal day at the Flynn Fletcher household, with the boys getting ready to go outside for the day and Candace lounging on the couch, talking to Stacy on the phone. It was winter, close to christmas, which meant no school for any of the kids today. Just like during the summer, the boy's were up to no good, making plans and crazy inventions that Candace was determined to stop. "So, I was with Jeremy the other day and-Stacy, I'm going to have to call you back." she was saying, hanging up her pink phone and putting it in her pocket. The boy's were up to something, she could feel it in her gut.

Candace walked over towards the window, looking outside and seeing the boy's sitting by the tree, like normal. The only difference was the layer of snow on the ground and the warm coats the boys wore. "Hmm. What are you up to now?" Candace asked herself, frowning at the boys. Deciding to give them a warning, she opens the door and shouts out to them, not wanting her plans ruined today. She was going to the mall with Stacy and she would not let the boys ruin her day yet again with their schemes. "I'm going to the mall with Stacy later today! You better not be doing any of your crazy schemes or I'm telling Mom!" she yelled, slamming the door after she finished.

Phineas looked up, smiling and waving at his sister from the yard. They had already done so many things over the summer that they were running out of ideas. Ferb had nothing and Phineas was struggling with thinking of something new to do in the snow. "Well, what do you think of this one Ferb?" Phineas asked, showing him a blueprint that he had in his hand. He had laminated them so they wouldn't be ruined in the snow, but none of them seemed to be up to their standards. After seeing the look his brother gave him, Phineas shook his head and sighed. "Yeah, you're right. None of these are good enough. What we need is something so huge, so fantastic that it can't possibly fail to give us an amazing day!" Phineas exclaimed, standing up and scattering the blueprints on the ground. Now, all he had to do was think of such an idea. Maybe things would get easier later.

Glancing around the yard, Phineas noticed something was missing. "Hey, Ferb, where's Perry?" he asked, remembering that their pet had been here just moments ago. Ferb shrugged, still waiting for more plans for the day. Meanwhile, Perry was hiding from the boys, slipping on his hat and sneaking into his lair for his assignment for the day. He leaned down near a flower growing in the snow, pulling it to lift up the hatch hidden beneath that led to his chair underground. He jumped inside, pulling the circular hatch shut as he slid through the metal slide. His ride ended as he landed perfectly in his seat and faced Major Monogram on the monitor for his assignment for the day.

"There you are, Agent P. Doofenschmirtz has been acting strange lately, purchasing large amounts of firewood and matches. We need you to get to the bottom of this and stop whatever it is he is doing." he said, knowing his agent would be able to handle the job. Perry gave him a salute, before heading off towards the house of his life-long nemesis.

Doofenshmirtz was waiting, knowing that at any time now his nemesis would be arriving. He already had his evil monologue ready and he would be very annoyed if Perry was late. As soon as the door was kicked down, the evil scientist turned around with a grin. "Ah, Perry the Platypus. I've been expecting you." he announced grandly, pressing a button in his hand and releasing his trap. Logs fell from above, surrounding Perry and creating a cage around him. "Ha! I've got you now. I hope you like my trap, it was inspired by the snowy weather lately." Doofenschmirtz said, walking over towards the cage to provide Perry with his monologue.

"Ah the snow. Children love to play in it, no matter where they are in the world. Many years ago, I had the same dream. As a boy, back in Gimmelstump, all I wanted to do was join the other children in their little games. I would see them sledding, making snowballs and snowmen, and think of how amazing it would be to join them. Unfortunately, I never got the chance to do so. I was trapped, stuck protecting the garden as a lawn gnome for my entire childhood. You remember that story, don't you Perry the Platypus?" he asked, nodding to himself as he realized that of course he would remember.

"Of course you do, anyway back to my story. The children eventually started picking on me, throwing the snow in my face while I remained still to protect our garden. I tried to join in, but my father wouldn't let me. This, Perry, is why I hate winter and the snow it brings! Thus, the snow-away-inator was born. It, well, it does what the name implies. Using the fire from thousands of matches, it sends a blast of heat so strong that it will eliminate all of the snow in the entire…tri-state area." he announced grandly, backing away to show Perry his inator.

He realized the issue, though. Perry could not see through the trap, it was a giant wooden box after all. "Well, I guess you can't really behold it from in there, but you do get the idea. Anyway, I'm going to use this inator to ruin the fun of children all over the area, then when they are so sad and lonely, I will rise and take over the tri-state area!" he completed, satisfied with his plan. He had gotten through the entire monologue without interruption. Today, he would finally win. Winter would not beat him this year, not again. He would have his revenge on all things cold and snow, and not even Perry the Platypus could stop him.
