A.N.: Okay, here ya' go! After writing my first PnF story, I got a bunch of ideas. This is one of them.
"Okay, Ferb. So, we've narrowed it down to these two creations: A Size changing ray or a Mind-reading helmet. So which one do we build?" Phineas asked his step-brother. Ferb looked over to him, then shrugged.
"Hey, Phineas," a sweet voice came from beside him. He turned and a young girl was lying on the grass next to him.
"Oh, hey Isabella," Phineas said to her.
"What'cha doin'?" she asked him.
"We can't decide whether or not to build a mind-reading helmet or a size changing ray," the boy told her.
"Well, I think the size-changer would be pretty cool," the girl told him.
"Okay then!"Phineas said. "I guess we'll build the size ray! Okay, Ferb?" he said as he turned to his step-brother, who had already gone and gotten his tools. "Hey! Where's Perry?"
Meanwhile, Perry, their pet platypus, wandered seemingly aimlessly into the kitchen. His eyes looked around the room, which was empty. He leaped onto his hind legs, and donned a fedora.
He ran over to the oven, and opened the door. He hopped inside and shut the door. The bottom of the oven slid away, and Perry dropped into his chair, located in his secret underground hideout. His attention immediately turned to the large monitor in front of him, on which a man was shown.
"Good morning, Agent P. Today, our other Agents have reported missing traffic lights in the entire tri-state area. I probably don't have to tell you anymore, considering it's always the same guy. Anyhoo. Go stop Doofenshmirtz!" the man said.
Perry saluted, and bounded for his hoverjet. He hopped in, and flew off, ready to do the one thing he does best: foiling Doofenshmirtz.
"Okay. We're finished!" Phineas said, looking at the large ray that stood on the lawn before him. "What should we try it on?"
"Can I try it?" Isabella asked him.
"Sure," Phineas said. "Just go stand in front."
Isabella ran over in front of the machine, its firing rod aimed straight at her.
"Okay, Isabella. Do you want to be big, or small?" Phineas asked.
"Hmmm…" Isabella thought. "I'll go with small."
"Okay, Ferb! Power it up!" Phineas called to the green-haired boy.
Ferb pressed a series of buttons, and the machine released a low hum. A bright green light materialized on the firing rod, gathering at the blue orb at the end.
"FIRE!" Phineas yelled. Ferb pushed a large red button, and the green light launched off of the rod, and reached Isabella. Next came a brilliant flash, and Isabella was gone.
Phineas got down on all fours and searched the ground Isabella was standing on.
He found her, a pink bug waving up at him. He set his hand down next to her, and she clambered up onto his hand with a great deal of effort. Once she was in his palm, he raised his hand up to him and Ferb.
"Voila!" Phineas shouted. "One insect-sized girl! We did it Ferb! We-" he stopped when he noticed Isabella had her hands pressed against her ears. "Oh," he whispered. "Sorry, Isabella." The girl nodded.
As Phineas spoke, a strong breeze kicked up, which to Isabella was the equivalent of hurricane-force winds. She was easily blown off his hand, and spiraled through the air. She hit the rim of a small hole in the ground. Try as she might, she couldn't prevent sliding inside. She fell, and hit the ground. Her head ached, and she saw shadows advancing on her, then she blacked out.
