Coat their entire kitchen with butter

At the stroke of midnight, Vivi woke up. She got dressed, went downstairs, and out the door. She met up with some friends.

"Ready guys?" Vivi said as one of her friends got out the mop.

"I was born ready." Harry said. "I can't believe I lived here."

"Ready to go." Ron said as he unwrapped something.

"Are you sure we should do this?" Hermione asked.

"Yes Hermione." Vivi said. "Harry, any chance of you coming back for the summer?"

"And help you torture them? Of course." Harry smiled.

"Let's rock this." Ron said.

The alarm clock in the master bedroom started to ring at 8:00 am. Vernon got up and turned off his clock.

"It's Saturday Petunia." Vernon said to his half asleep wife. "Are we going out to breakfast dear?"

"Not until Vivi's settled in." Petunia groggily.

"Vivi! Merlin's beard. Who knows what that girl is going to do today."

Petunia immediately sat up. "We better go check and make sure she hasn't set anything on fire."

Vernon was out of bed in a flash. Petunia threw a bathrobe on. On the way down, Petunia checked to see what Vivi was doing. Vivi was sleeping soundly. Petunia walked over to the girl and tapped her.

"Vivi, time to get up." Petunia said softly.

"Go away." Vivi mumbled.

"Come on. Bacon and pancakes for breakfast."

Vivi sat up. "Fine, I'll meet you downstairs."

"Vernon, get Dudley up." Petunia shrilled as she left the room.

"Up boy." Vernon said as he shook Dudley. "It's Saturday."

"Bacon." Dudley muttered as he got out of bed.

The phone rang. Petunia ran down the stairs.

"It's for me." Vivi called. She hopped over the railing and grabbed the phone.

"Vivi, you better not have ruined my railing." Petunia warned.

"Relax Petunia. Oh, and I'm fine thanks for asking." Vivi turned her attention back to the phone. "That was fun. We have to do that again sometime."

Petunia shrugged it off. Vernon and Dudley glanced at Vivi but shrugged it off before joining Petunia.

"Who's she talking to?" Vernon asked, nodding at Vivi.

"I don't know."

Dudley went right up to Vivi. He put an ear by the phone.

Vivi swatted Dudley away and said, "No, that's just Dudley. I know you're in the kitchen."

"Petunia, just make breakfast please." Vernon begged.

"I know right?"

Petunia turned on her heels. She went into the kitchen and a thud was heard.

"Vernon!"

The pudgy man ran to help his wife. "VIVI!"

"I got to go. Yep, they found the kitchen."

"VIVI!"

"Dude you don't have to yell I'm right here." Vivi said while she poked her head through the doorway.

"How did you do this?" Petunia made a sweeping gesture around the kitchen.

"What makes you think-"

"We know you did it girl." Vernon growled.

"I have a name." Vivi said.

"It's Vivi." Dudley stated.

Vivi glared at him before saying, "Did I tell you my friend, Harry, is staying here too?"\

"No you didn't."

"Well, you know now."

"Wait a minute!" Vernon said. "Wait a minute! Harry who?"

The doorbell rang. Vivi turned and got the door.

"What a surprise they're going to have." The Dursleys heard Vivi say.

Dudley looked through the doorway. He ran back to his parents, slipped, and ended up on his back. He licked his hand and said, "Delicious."

"Dudley, don't." petunia said firmly. "Who knows where's that has been."

"Guys, you've met Harry." Vivi said.

"Hello aunt, uncle, cousin." Harry greeted cheerfully.

"POTTER!" Vernon shouted.

"Dude you don't have yell we're right here." Vivi and Harry chorused.

"What are you doing here?" Dudley asked.

"I lived here." Harry stated. "And Vivi's my friend. So I'm spending the summer here."

"Oh no." Petunia moaned. "As if one of you wasn't enough."

"Clean the kitchen." Vernon demanded.

"I think Dudley's got that handled." Harry pointed to his cousin.

Sure enough, Dudley was on his hands and knees lapping up butter.

"Dudley!" Petunia shrilled. "

Vernon grabbed his keys and said, "Come on. We're going out to breakfast."

Petunia and Dudley followed him. The door shut then opened.

"Oh no, I'm not leaving you two alone in the house." Vernon said. "I don't need the house blowing up."

"Why didn't we think of that?" Vivi whispered to Harry as they walked to the car.

"We have all summer." Harry reminded her.

"So true."
