Kiba:
Put dog food in his meals

Naruto had serious questions he wanted answers to. One was why did Ichiraku ramen taste so good and the other was recent. He hadn't thought about it until a couple of days ago while he was on a mission with Kiba, Hinata, and Shino. The night when they were eating, Naruto saw that Kiba would feed Akamaru some of his meal. Did that mean it was the other way around? After all, Kiba was part dog...right? The blonde was dying to know the answer. If Kiba ate dog food, that definitely meant he was part animal.

The sixteen year old sat in his messy room trying to come up with a way to see Kiba's reaction to dog food. If he just asked him to eat it, there was no way the Inuzuka would allow himself to willingly consume Kibbles N bits. Wait, no; Naruto wouldn't use dry dog food, he would use the type that actually looked like regular people food! He would warm it up and everything.

Naruto smiled to himself at his plan. All he needed now was an idea to feed it to Kiba. How would he make him eat it without knowing? Akamaru would be able to tell if it wasn't actually human food and it would probably be the same for Kiba. It seemed like he had hit a brick wall in his plan. How would he get around the fact that those two would be able to smell something was off a mile away?
There was a strong knock at the door and the Jinchuriki stood, kicking empty containers of ramen and dirty clothes out of the way in order to clear a path. Upon opening it his door, he came face to face with Sakura.

"Hey Sakura, what's up?"

The pink-haired girl gave him an excited smile and said, "We're going to battle against Kurenai-sensei's team this afternoon at two o clock. Even she and Kakashi-sensei are going to spar so you better be there."

Naruto began giggling maniacally to himself. This was the perfect opportunity to execute his plan. After they fought, everyone would be hungry. If he offered to make something then that would be the easiest way to get Kiba to eat dog food. By his reaction, Naruto would know if he was just like a dog or not.

"Sounds like fun!" the blonde exclaimed. "Afterwards we can have a picnic. I'll pick up some stuff from town for us."

Sakura scrunched up her nose. "Are you going to get everyone ramen because I-"

"No," Naruto interrupted quickly, reaching a hand back to scratch the back of his head. "I'll just um...get ramen for myself! Yeah that's it! No one likes ramen more than me after all!"
She rolled her viridian eyes before turning to walk away. "You've got that right. See ya later Naruto!"

Said ninja returned to his room in order to get his wallet. It only took a moment and Naruto was out the door, but had to return because he had forgotten to brush his teeth. Stopping to think before leaving again, the knuckle head ninja remembered to grab his weapon's pouch for later and headed out into the bright sunlight. It only took a moment for Naruto to submerge himself deep in the streets of the market and soon he was buying meals for each person who would be at the battle. Everyone except Kakashi-sensei anyway; he always was skipping out on paying for his meals so there was no way Naruto was going to pay for his food yet again.

So far he had something for all of Kurenai-sensei's team including the meal that would be replaced with dog food for Kiba. Then he had a packed lunch for both Sakura and Sai as well. Now there was only the task of buying himself something and getting the item for his scheme.

Naruto was laughing quietly as he continued moving through the market. This plan would be foolproof. All he had to do was switch the meat with the dog food and see what happened when Kiba ate it. He still worried a bit about the brunette or his trusted companion sniffing the difference, but maybe he would get lucky and they wouldn't notice.

After buying his ramen and having it put into a container he had for when he couldn't eat at Ichiraku's, the young ninja then got the last item he needed. He returned home in order to warm up the puppy food and replaced it with the meat that was in one of the meals he had bought. In order to make sure he didn't get confused, Naruto placed the lunch for Kiba at the top of the bag.
Gazing at the clock, Naruto saw that it was almost two now. It looked like his trip to the market had taken about thirty minutes and now he was ready to head towards the training grounds.

The battle between teams ended up with a draw. Each match was five minutes long and it was decided by Iruka-sensei, the one who had been the referee, who won if there wasn't a clear winner. Naruto of course won his fight with Kiba although the accidental advantage he had gotten in the chuunin exams didn't work. He had a cold and his nose was stuffed up so he couldn't smell any of the rotten gases that seeped from the blonde's backside; luckily that still worked in Naruto's favor. Now the chances of Kiba sniffing out the dog food would be lessened.

After the sparing match, Naruto handed out the lunches he had brought, pausing to congratulate Hinata for beating Sakura. He was really proud of her for that; she showed everyone how much she had improved and although she didn't win without injury, the quiet girl still did great. Not only that, but the Hyuuga princess looked prettier to him today. In fact, he never noticed that she was pretty at all until a few days ago.

Their meals had grown a little cool, but it was still a bit warm and everyone else began digging in. Kakashi turned to Kurenai-sensei and asked, "What was that jutsu you used? I don't think I've seen something like that before."

"Do I hear someone being a sore loser?" the Jounin asked her fellow ninja, a smile breaking over her red lips while she picked up her chopsticks and began to eat.

"Never," Kakashi mumbled. His attention turned to their little group and he realized he was the only one who hadn't been brought lunch. "Where's mine Naruto?"

"Go buy your own sensei!" Naruto exclaimed, blue orbs flashing. "You're always skipping out on paying for your meals so if you want something, go buy it!"

The Copy Ninja sighed. "And here I thought you cared about me." The masked man stood and waved. "See you later."

With that, he disappeared in a puff of smoke. Naruto turned his attention back to Kiba, who was opening his lunch. This was the moment the blonde had been waiting for and he swallowed thickly, his heartbeat pounding in his ears.

Suddenly, Akamaru began barking and Kiba looked at his dog. "Yeah right, I'm not falling for that again."

"What's wrong Kiba?" Hinata asked.

Said shinobi frowned at the large white canine. "He's trying to tell me that this has dog food in it. He told me that before and it was only so he could get my food. Well, you aren't going to fool me again Akamaru!"

The dog began to whine in response and Kiba flat out ignored him. Naruto had to stop himself from acting giddy with the turn of events. He had gotten so lucky because if Kiba had believed Akamaru, his whole plan would have been thwarted. It was a good thing that Kiba was very stubborn.
Tasting a small piece of the meat first, Kiba didn't find anything wrong and continued eating. "This is good. Where'd you get it from?"

Naruto stood up and pointed a finger at the male accusingly. "See! I knew it! You are part animal because only dogs like dog food!"

Sakura choked on the piece of broccoli she was trying to chew. After a few claps on the back from Hinata, the kunoichi was able to breath and asked incredulously, "Naruto, you really put dog food into Kiba's meal?"

"I wanted to see how he would act after eating it!" he explained. "Since he likes it, he's just like a puppy!"

Shino gazed at the food in front of him. "Naruto, did you put dog food in our meals as well?"
Immediately the others began spitting out their lunch while Naruto tried to explain that he didn't do anything to anyone else's food. It was too late from all the angry expressions he was receiving so the Jinchuriki turned and high tailed it out of the woods. He knew he was caught when he heard, "Wolf Fang over Fang" shouted from behind him. This wasn't going to end pretty at all.

I like having a character running off in fear lol. Next person doesn't seem to know how to die. I wonder if you'll figure it out.
