Planning a Prank (OPEN)

Sitting quietly by herself, Alyssa looked through a big textbook, trying to find the perfect spell to make her prank work. She wanted it to be amazing, and she didnt want the teachers to reverse it before it could really take flight...litterally.
She wanted the chicken and turkey at dinner to suddenly stand up, and act as if its alive, even though its still cooked and most likely headless. Then the roasted birds where to take flight when the owls came into the great hall. It's briliant, she thought now i just need the perfect spell to stop the teachers from reversing the potion
She had spent a great portion of the day working on a potion that a few drops on the top of each bird and they will 'come alive'!
She was concentrating so hard, she didnt notice someone looking over her shoulder at her notes untill they started talking.

"Whatcha doin'?" asked Casey. She flew backwards as Alyssa jumped, nearly hitting her eye. "Jeez, I thought you knew I was there! Whatever happened to super senses?"

Alyssa jumped when she heard a voice right next to her ear.
"You know when I'm concentrating hard, that I dont pay attention to that, and you wouldnt either, if you had my nose, or every 8 seconds your head would pop up, because you heard somthing, or smelled chocolate on someones breath, or felt footfalls coming somewhat towards you! It would drive the sanest man insane! And you know I am far from sane to start with! Just think where that would leave me?!?" Alyssa said most of it with a straight face, but then started laughing at the look her sister was giving her! ...and speaking of her sister, Alyssa smelled chocolate on her breath.
"When did you have chocolate, and why didnt you give me any?"

"First off, I had chocolate 5 minutes ago, second, I didn't know where you were, and third, try having colors flitting around on the edges of your vision all the time and know exactly how people feel all the time (which isn't exactly a good thing). Oh, and here." She threw a chocolate frog on her sister's lap. "So, what are you doing?"

Alyssa laughed, and took the chocolate frog,
"Thank you! And you know that vision thing totally comes in handy when you play poker" Alyssa took a bite, and glanced at the card, Harry Potter intresting.
"I missed you, and I have an idea for our next prank, but it'll take some planning."
