I don't own HP or Phineas and Ferb.

Ring! The alarm clock rang. Phineas got up and hit it on the spot.
"Good morning Ferb!" he greeted his step-brother, who was changing his t-shirt. "I wonder what to do today," he said as his t-shirt was striped with orange horizontal lines with the help of his "Liner Machine". Ferb's stomach gradually grumbled. "I know, I'm hungry too. Come on, slow poke! Let's eat," They slid downstairs and landed as a pile of heap.
"Good morning boys," their mother greeted. "There were letters for you." She handed them an envelope each.
"Phineas Flynn
1398 Elm Street
Room across from the Bathroom
Danville, Tri-State Area
USA," Phineas read on the back of the envelope. "How on earth did they know that our room is beside the bathroom?" he asked Ferb, which gave him a shrug in response. "Oh well, let's see what they wrote,"
"Dear Phineas Flynn,
You have been accepted to go to Hogwarts School of Witchcraft and Wizardry. The first term will begin in September first, and a list of the needed items is enclosed at the back. Your train to Hogwarts will be at King's Cross.
Yours truly,
Professor Albus Dumbledore
Hogwarts' Current Headmaster"
"King's Cross? That's in London!" Ferb exclaimed, which pretty much surprised Phineas.
"Then we'll have to leave very early," Phineas suggested. Their mother was listening to what they were saying and said, "But Phineas, you're enlisted in Elmore School, we can't just say you quit."
"But mom," Phineas pleaded, "it's a once in a lifetime opportunity. If we back out, we may never get to do so again,"
Candace, who had been listening also, seemed wildly exaggerated.
"Oh puh-lease," she said, "there's no such thing as magic."
"Then how'd they now we sleep across the bathroom?" Phineas protested.
"Okay, maybe it was just a prank," she snapped back.
"I don't know, Candace."
Just then, their friend Isabella burst in the living room.
"Phineas! You would never believe what I just got! It's a letter from Hogwarts, only the most amazing school of magic EVER!" she exclaimed.
"See?" Phineas taunted at Candace, and she said a nasty reply in return. "Maybe you are all so easily believing on things that they targeted you both for their precious Pranking School,"
"Hogwarts is not make-believe," Isabella snapped.
"Oh really?" Candace hissed, "Prove. It."
"It only accepts children at the age of eleven and they have to have some good wizardry skills,"
"And…?"
"And you gotta look at this," Izzy said and threw a book at Candace. She cought it and read, "'Hogwarts: A History'," she rolled her eyes, "whatever," then dropped the book, which fell into Isabella's hands just in time.
"It also says in here there will be a guest coming at 8:00 am sharp to explain all the important stuff to us," Phineas read at the very end of the letter.
"Well, then. Let's eat and wait whether he'll come or not," Ferb said and the trio went inside the kitchen for bacon.

Well, do you like it? The next chappy will come out in a jiffy, so be prepared for this guest's appearance! Guess who? Three options:
a. Dumbledore himself or
b. Hagrid and/or
c. McGonagall!
So make your choice and wait for the next chapter! BTW, here's a preview:
Chapter Two Preview
Phineas sat on the couch with his friend Isabella and his best friend/step-brother Ferb by his side. It was 7:59, and there was still no one by the doorbell.
"Aw," Phineas said, disappointed, "I guess it really was a prank,"
Then a sudden knock made them jump. They exchanged nervous glances at each other before pulling the door open.
I chose to cut for suspense! XD! So bye bye for now and
Review!
