Chapter 6

Harry wrote down what Sirius told him. When he was done he handed the paper to Sirius. Sirius re-read it and handed it back to Harry and smiled.

"Ok, would you like to learn to prank before dinner?" asked Sirius with a smile.

"Really!" asked a very surprised Harry, shouldn't all adults be really strict and say no to pranks, yet again this was Sirius they were talking about.

"Yes I am," said Sirius with a smile which turned into a 'I am plotting chaos here' smile, "Harry……"

"Yes Sirius, what is it?" asked Harry a bit nervously, what was his godfather up to?

"Do you remember who is still with use? Even if they are at the over wing of the castle and the wing for muggles at that?" asked Sirius slyly.

"Yes, the Dursleys, but what has that got to do with….." Harry trailed off then he looked over at Sirius, which Harry matched his grin of mischief, "We are going to be pranking the Dursleys?"

"Got it in one!" Sirius said happily "So what do you think we should do to them?"

"Nothing," Harry said and at Harry's answer, Sirius fell off of his seat and looked up at Harry with a VERY shocked look on his face.

"WHAT!" yelled Sirius in shock. He thought that Harry would want to get his own back on his relatives for all that they had done to him.

"We get Dobby and Winky to do the prank for us," Harry said with a big grin causing Sirius to mirror his big grin.

"Oh great master of pranking what do you have in mind?" asked a surprised Sirius, Harry's plan was perfect in his opinion, they could prank the Dursleys and no one would ever know it was them as they was on the other side of the castle.

"Watch and learn, I've been planning this for a long time," Harry said as Sirius managed to climb back into his seat.

After listening to his godson, Sirius Black was shocked. He just couldn't wait to see what his precious little godson had thought up to prank the Dursleys with. So he nodded his acceptance to Harry.

Harry seeing Sirius's nod, called the two house-elves that seemed to only answer to his call.

"Great Master Harry Potter called?" asked Dobby as he and Winky appeared in front of them. Sirius yet again fell of his chair laughing at the title that the two house-elves had given Harry. Harry just gave a mock glare at his laughing godfather.

"Dobby, Winky in my trunk there should be a potion vile with a light-blue liquid inside it, it's for the Dursleys as they have asked for it, could you please mix it in with there food and drinks please?" Harry asked politely.

"We will get right on it great master Harry Potter," Dobby said with a bow so low that his long ears and nose touched the floor.

"Oh and after they take the potion you might need two VERY big tanks of water," Harry said, trying not to laugh as he talked.

"Yes master Harry Potter," Winky said while bowing like Dobby. She knew what these Dursleys were like and she had a feeling what the masters was up to but she wasn't going to stop it, in her option, those horrible muggles deserved what ever this light-blue potion.

When Dobby and Winky had popped away, Sirius turned to Harry and asked him with laughter in his voice: "What will that light-blue potion do to them?"

"Well,…depending on the dosage and the amount of food and drink that they consume.."

"Which will be quiet a lot," Sirius butted in getting a sound of agreement from Harry, which he then continued his expiation.

"Then the effects will last depending on the amount of potion that they consume, which for my 'dear' Uncle and Cousin is a lot then it will be a long long long time. So lets just say that we could be returning from Hogwarts this time next year and they would just be starting to show signs of returning back to there 'lovely' selves."

"That's great Harry!" Sirius said which made Harry blush, "So what does the potion do?"

Before Harry could answer, a loud giraffe like scream could be heard coming from the muggle wing.

"What the hell was that?" Sirius shouted in shock. Hearing Harry laughing like mad, Sirius turned to Harry still in shock "Harry…"

"That was the potion at work," Harry said between laughs making a understanding look appear on Sirius's face.

"What did you do?" asked Sirius, wondering what could have coursed that horrid screech.

"Why don't we go and have a look?" Harry asked, he loved making wonder what he have done to the Dursleys.

Harry and Sirius got up off of there seats and walked up to the muggle wing of the castle. As they walked though the corridors, they could hear a sobbing sound and some angry sounds coming from the room that the Dursleys was last seen in. Sirius wondered what was causing those sounds as it sounded like a mix between a human and an animal making them.

As they reached the door to the room, Harry opened the door and when Sirius had seen what Harry had done to the Dursleys, there was no doubt in Sirius mind that Harry was the son of Prongs.

There in the room was all three Dursleys, or what was the Dursleys. The results of Harry's prank had made them turned into……
