Spike enters Rarity's boutique for a single request. "Rarity, oh thank Celestia, I need your help with something.", he said.
Rarity was measuring a couple dresses with her paper ruler. She stops and turns around to see Spike standing at her door. "Spike!", she said cheerfully. "It's good to see you at this time of day."
"I heard you were part of Twilight's prank she did on me yesterday.", Spike said, raising an eyebrow and hoping that Rarity would give in.
"Ok, you got me, I did help Twilight with her prank she did on you.", Rarity said. "All I did was make the prison outfit for Big Mac and he pretended he escaped from prison."
"And I was thinking that you should help me, just like how you helped Twilight.", Spike said.
"But, how am I going to help you?", Rarity asked. "What I did in that prank was made a prison outfit for Big Mac."
"That's why you don't have to.", Spike said. "Outside your boutique, I made a cardboard box that's the size of Twilight when she lays down." He turns his cheek to Rarity and put one hand to a side of his mouth. "I want to make Twilight think she's been buried alive."
"Oh dear, you want to make Twilight think she's buried alive?", Rarity asked with a gasp.
"Um, yes.", Spike said. "Why, do you not think it's a great idea?"
"No,... I think it's a brilliant idea.", Rarity said. "Now that it's night time, it would be the best time for us to do it."
"Alright, Twilight goes to bed at nine o'clock, so right now it's nine eleven." Spike said. "Lets do it. Oh, and one last thing."
"What is it, Spike?", Rarity asked.
Spike took Rarity's face, brought close to his, and scrunched his nose against hers. "I want you to carry the box, stick behind me and don't make a sound.", he said. "Is that clear?"
Rarity nodded. "Of course I can, Spikey-wikey.", she said.
"Good.", Spike said. "Lets do it."
