Equestria's "Cold Blooded Assassin"

"Really man? How are you gonna fit the tail in there?"

"Says the one wearing the jetpack."

My friend, Jeffrey, and I were trying to fit into the small car of his with the parts of our costumes, both of which are based off of Dragon Ball Z, as we were going to a local convention, since it was the first time it was in our town. I was going as Imperfect Cell, and he was going as the "mighty" Hercule, in the outfit from the first Budokai game, which is why he had a jetpack on, and why I had a tail.

"You also have wings, so don't get upset about stuff on MY back." He said while I got into the back by sitting sideways.

"So, why did you pick the weakest character in Dragon Ball?"

"I'm not Krillin."

"Touche." I said while trying to stop myself from laughing.

"So, any plans here?" I asked.

"Same thing we always do at Cons."

"Try to take over the world?"

"Really? I knew you were old school, but Pinky and the Brain?"

"Yeah. Anyway, what is the plan?" As I asked, I saw him put his wallet in his Jetpack.

"Mainly just check out the vendors."

"How much money do you have?"

"Around 60 bucks, last time I checked."

"Well, I have about..." I checked my wallet "80 Dollars. Where am I going to put my wallet?"

"I'll hold onto it, I guess?"

"Nah, I'll just keep it in my hand."

At this point, I had gotten out of the car (With some difficulty thanks to my tail.) "Ok, split up and-"

"Search for clues?" He interrupted.

"And you said I was old school. Ruh-Roh! Soda is 3 dollars a can."

"Well, it IS a convention. Hey, what's that guy selling?" I said as I pointed at a large stall, manned by a man dresses as Mr. Popo. "Are those Dragon Balls?"

"Yes. I have things from a lot of Different shows, my friend."

"How much?" Both Jeffrey and I asked.

"For how many?"

"All of them."

"Around... $140."

As we both looked at each other, we knew we had it. "Deal."

"Very well then, my friend. step on the carpet. For authenticity, of course."

As we stepped on it,  we handed him our money, and he handed us a box that had all seven of the Dragon Balls. Almost immediately, I felt the carpet... Move? I looked over at Jeffrey, and he looked as surprised as I probably did. Then, he disappeared.
