Here is my second story! I know I haven't updated the first one yet, but patience young ones. I have seen a lot of fanfics with Kululu, and, seeing that he is one of my favorite characters, I decided to do this. I don't know if it'll be that good, because I think Kululu is really weird and mysterious, and because of that I don't really know him. Oh, and one more thing, I DO NOT SUPPORT GIRORO X KULULU! That's not what this fanfic is about.

DESCLAIMER: I do NOT own Sgt. Frog/Keroro Gunso

It started like any other morning, and the morning sun was just about up. Sparrows chirped their morning song, as they flew by one particular house. Inside that house were two kids, Natsumi and Fuyuki. They were dressed in their uniforms, ready for school. Although it seemed like a normal day, it wasn't when a certain green frog started jumping around and singing:

"No chores, no chores, I've got no chores!"

"If you make us late there will be chores for you… all week!" replied Natsumi, she was getting tired of his care-free attitude. "Hey Fuyuki, do you want eggs?"

"No, at least not now; whoo that was a lot of work." He was trying to take out the trash, but with his poor un-athletic body it was pretty difficult.

"How far did you get it this time?" called Natsumi form the kitchen.

"It's on the front door mat!" Fuyuki hollered back, with sparkles in his eyes.

"Fuyuki-dono I was wonder if maybe today-!" Keroro started, but suddenly a trap door opened and he fell right through.

"Sarge, are you okay?" Fuyuki looked down the trapped door.

"He'll be fine, just hurry up and eat; before we're late."

That's when it started to get freaky. Suddenly, red lights were flashing and sirens were going off. It was such a startle, Natsumi screamed at the sound, hoping to get it to stop. The only one who actually heard this scream was none other than Giroro, "Natsumi?" He called out, but when he couldn't get the back door to unlock he decided to bust through it. "You're so predictable!" a strange voice hollered. That's when bolt doors were placed in front of the other ones. The sirens started to go down; about the same time the red lights stopped flashing.

"WHAT THE FROG JUST HAPPENED?!" Natsumi yelled, well, everywhere. "There's no time to waste, we have to get to school; wait a minute…" that door also had an iron door that was bolt shut. I have an idea about who did this. She thought to herself.

"Wait Natsumi, I don't think Sarge is capable of doing this," Fuyuki defended his Bro-hiem.

"Then who else could've done this…" Natsumi wondered…

"KULULU," they both agreed.

"Wait till I get my hands on that frog, I swear I'm going to snap him in half for making us late. Also,-" Natsumi started, but then she was cut off quickly.

A "KERO~" was heard throughout the household. Everyone got goose bumps, and a big shiver went down their spine. Something told everyone that Kululu was acting a little more abnormal than usual.

"Should we go check it out?" asked Fuyuki as he was rubbing his arms.

"I don't know… whatever it was, I'm sure that stupid frog deserved it."

Before Fuyuki could think of a good enough answer to out-smart his smart sister; they heard another scream:

"I SWEAR I DON'T KNOW~!"

"Forget about the frog," Natsumi stated, "I'm more worried about us, so let's go check it out."

They ran down the small corridor to Keroro's room. They slowly opened the door only to meet with... darkness; nobody was there. Well nobody, except for Omiyo the ghost. She was shivering as well.

"I've seen the yellow one before, but this time he is being extra scary. He's down in the base… in his lab. By the way he dragged the green one down there as well." Then she quickly floated into the left wall; where the shadow of the body was.

Fuyuki opened the small refrigerator door; he glanced back wondering what was ahead of them. They were expecting a blinding light, but instead were, again, greeted with darkness.

"Well, ladies first… right?" Fuyuki asked. Natsumi just shook her head, and pushed him in.

"Which way is Kululu's lab again?" Asked Natsumi; she lead the way ready for anything.

"I don't know; I've only been in there once or twice. Plus I can't see with out any light. Maybe if we split up we can-"

"Shh; shut up, and listen," Whispered Natsumi as they both stopped in total darkness; not wanting to make any sound.

"Ku…ku…kuu" it was soft, and it sounded sad. They didn't think it was Kululu, until they heard a huge explosion afterwards.

"This way!" they ran down a hallway, stopped. Then they ran faster than before, not wanting to lose the sound, until they heard a door open. "Quickly, before we lose it again!" hollered Fuyuki as he dragged behind Natsumi.

"Gosh, little bro. we really need to get you into shape."

"Lets not talk about me being a wimp right now; Sarge could be in trouble!"

"Or worse… we're in trouble!"

Both of them ran through the door, but heard a big "BAM" when they entered. "What was that," asked Fuyuki.

"I smashed into a wall…" Her voice had a hint of shame in it.

They walked around, tripping on wires and broken guns. They heard noise, but they couldn't make out what it was. Although, they did see something; it was a small yellow keronian in the fetal position.

"Kululu is something that matter- OH MY GOSH!" Fuyuki screamed.

"What is it," Natsumi got closer, "Something isn't right here… WAIT!"

The siblings both stared in horror at what was probably the most shocking thing they had seen."

"Don't say a word… or you will be tortured just like the sergeant." Kululu pointed at a single chair, with Keroro tied up in it; tears running down his face. "I will find it." Kululu stated. "I will"

THAT WAS SUUPER LONG! Haha anyways, I wonder what Kululu is looking for? Those of you thinking when I'll be able to update the story: "Let him go?" Just sit back and let me do all the thinking. Plus I've had some stuff going on so I really haven't been able to type for that long. I typed another story so you have something else to look forward to, besides Giroro x Natsumi. Oh and one more thing, I am taking request if you want me to type something for you, my WONDERFUL reviewer. I will only choose the ones that won't take long to know what I need to start with, and how it needs to end, and tell me if you want it in chapters or just one LONG story! NO WIERDO COUPLES LIKE: Saburo x Natsumi, Giroro x Dororo, or anything like that. I think that's it, sorry this author's note is so long, but I just want you to be on your toes for this stuff! SEE YOU NEXT TIME!
