Eek! I couldn't get this out of my mind. So here is is.

"So, Buu." Hercule Satan said, patting the big pink gumdrop. "Whenever you beat everybody at the tournament, you will be facing me as your last opponent."

Buu had his hand in his mouth, and was giving the huge man in front of him noises for answers.

"When we face, you have to let me win." Hercule finished.

"Hmm." Buu murmured.

Mr. Satan rubbed the back of his neck bashfully. "I know it seems unfair, but I need you to do that for me."

"Mmm." Buu was halfway paying attention. One half was alert to what his friend was saying, but the other half was thinking about candy.
Gumballs? Jolly Rancher?

"It's not that hard. All you have to do is let me punch you, and you fly out of the ring." The nervous man was talking faster.
Is he going to listen to fall for it?

NO! Chocolate!

"So, how about it?" Hercule let out a laugh. He always laughed when he was nervous.

"Why can't Buu no hit you?" The childish Buu asked.
YEAH ICE CREAM!

"Because I need to stay inside the ring. You see, Buu, if I don't win, everybody will know I'm fake. And then I will be unhappy. And made fun of."

"If meany men do that to Buu's friend, Buu will get mad, and make meany men dead!" Buu concluded, giggling.

That was when Hercule got an idea. He needed to straighten things out with Buu, like he promised to Vegeta and Goku. And his own plans mixed with it.
I can use this to my advantage!

Cotton candy. Buu thought.

Hercule did what he was best at. Acting.

"BUU YOU DON'T EVER GET MAD." He yelled.

The startled Buu forgot all about his candy, and was startled. He scratched his head. "Why Buu not able to get mad?"

"Because of what happened last time. We don't want that all over again, now do we?" His voice was calmer now. He had Buu's full attention now. He patted the pink man on the back.

"Oh. ok. Buu won't get mad. Buu will be sad if Buu made and evil Buu again. Buu will let Mr. Satan win so Buu won't get mad." Buu figured out in a way that only Buu could.

"Thank you, Buu." On the outside, he was calm and understanding. But on the inside:
Yay! I have done well. Again.

"Mr. Satan is welcome. But Buu has one question."

Hercule grew nervous again. "Y-yes?"

"If Buu make it look like Mr. Satan wins fair and square, can Buu have candy?" It was said with such innocence.

Aww, I think I should. Buu deserves it. I mean, I'm asking a lot of him. I love him.

"You know what, Buu?" Hercule said in an honest soft tone.

"Hmm?" Buu replied.

"Yes. Yes you can. As much of it as you want." He said with an ever expanding heart for his closest friend. He put his arm around Buu and they started to walk out of the room.

"YAY! BUU GETS CANDY!" The round man said.

Hercule smiled.

"Oh, and can Buu have ice cream?"

"Yes. You can." His voice started to fade as they got further from the room.

"And Jolly ranchers?"

"Mmhmm."

"Ooh, and chocolate?"

"Sure, Buu."

"And..." was the last thing before you could hear no more.
