Halloween
"Hey Ferb! Are you ready to go?" Phineas yelled, waiting by the door for Ferb to appear. Like every year, they kept their Halloween costumes secret until they were ready to go trick-or-treating. This was very hard to do until a year or two ago, when they had built an invention that could make any outfit or costume appear out of thin air. They had been worried about using it at first, since they had heard most machines like this stole stuff from surrounding shops. But after many tests and phone calls, the machine was proven innocent enough, and they've used it ever since.
Phineas was proud of his costume this year. He was completely covered in a multicolored powder that made his skin that made his skin look like it was rotting. It was designed not to smear or rub off, or even come off at all until he took a shower. He had used something special to make his skin sag, as if it really was rotting. He wore a ripped, long sleeved shirt. It looked as if it was once white, but now it was smudged with dirt and other things, turning it brown and yellow, and was also splattered with fake blood. He thought about adding a jacket to keep himself warm, but he decided to add a built in heater instead. He did the same with the ripped, dirty jeans he wore to match.
Phineas ran down the stairs and smiled at Phineas. He was fully covered in shiny silver metal. His eyes were red, and dimly glowing. His mouth covered by a square now, with static lines going through it, making smile look weird since the lines were smiling to. The body was thick and rectangle shaped. It looked like something Phineas and Ferb may have built when he was board, with many hidden traps hidden inside. The arms were skin tight, and ended with pinchers. His legs were gone, replaced by a hovering device of some kind. Phineas smiled back at his brother, impressed by his work.
"Nice!" He said, sounding as impressed by Ferb's work as he felt.
Ferb nodded, obviously saying "You too."
A smile suddenly broke through the usual blank look on his face as he remembered something. Phineas looked at him curiously, wondering what was so funny.
"Hey Phineas, I have something else to show you. I think you'll like it!" Ferb said excitedly. Phineas didn't have any time to reply. Ferb had already disappeared upstairs. Phineas stood there in silence, feeling more impatient than he had a minute ago. What did Ferb think was so special? It took Ferb a few minutes to find what he was looking for, but as soon as he did, he ran down the stairs as fast as he could in his costume.
Ferb held Perry in his hands, but there was something different about him. It took Phineas a moment to realize what it was, but when he did notice it, the smile was whipped off his face. he glared up at Ferb, who was now laughing his head off at Ferb. Perry had bunny ears sticking out of his head, looking out of his head, looking like they've always been there.
"I finally found the Easter Platypus, Phineas!" Ferb tried saying between laughter.
"Really Ferb? I thought we were done with this!" Phineas yelled, playfully pushing his brother, forcing him to drop Perry. He didn't really notice though. He pushed Phineas back, and they both ran out, with their platypus close behind, all ready to trick or treat.
Sorry that this is a little late. I couldn't really think of anything to write at first. I ended up writing this. I hope you like :D
