This is my Kico story. First five chapters are already on FFN. Enjoy, and review in the comments!

Kowalski lifted the Beaker. So far, all seemed calm. He slowly tipped the beaker. So slowly, in fact, that only a single drop came out. It fell into the bronze liquid below. Smoke, the proof of the mixing of the chemicals, arose. The mixture turned a blood red colour.

It was ready. The ultimate cure to diseases – Immunity Enhancer 2.0. The 2.0 just made it sound cool. Which it was. This could help AIDS victims and Cancer Patients everywhere! He let it sit.

Skipper came in the room. "Kowalski, you're on Recon." He said.

"Alrighty, Skipper." He set the liquid in a cup, and headed out the door.

A few Minuten later, he came back. "All's good on the Home front, sir." He said.

"Good." sagte skipper. "At Ease."

Kowalski headed back to his lab. There was a container of saft there, which he drank. He looked over at his new invention. It was a fantasizer, a machine that allowed Du to relive vivid fantasies in your head.

It was about ten o'clock, and he was very tired. "I'm going to turn in, Skipper." He said.

"Kay." He replied.

Kowalski walked over to his bunk. Suddenly his head hurt. Maybe he would feel better in the morning.

He didn't.

Kowalski opened his eyes. He felt – lighter. Less stockier. His chest felt very heavy though. He thought nothing of it. It was probably just a cold oder something. He walked to the bathroom. Flussshhh. He rinsed his face, and dried it with a towel.

BRRR! He thought. He finally looked up into the Mirror.

He shut his beak to keep from waking everyone else. They would be alarmed as soon as they heard his voice. It was different, he knew that. Everything about him was different.

Because he was female.

What the heck had happened? A knock came on the door.

"Uh, busy!" he responded. "Aghuh!" Rico sounded surprised. He heard feet walking away, and Mehr feet coming back. "Spy, what are Du doing in there?"

"I'm not a spy, I'm Kowalski!" he responded. "No. Kowalski has a manlier voice than that!" Kowalski sighed.

He opened the door. "I AM Kowalski. Female version."

Private fell through the door, the other two penguins standing behind him.

Skipper still wasn't sure. But he was willing to take a chance. "If you're Kowalski, what did I sing to Du on your birthday?"

"Nothing. I didn't have my birthday yet."

"Well, then, Kowalski – what is going on?"

"I don't know, Skipper. Last night, I had some juice- OH!" He slapped his forehead.

"I must have accidentally drunk the Immunity Enhancer 2.0! It must have changed all my Y-linked chromosomes into X-linked!"

"Well, get working on a cure – and stat!" The three of them walked away from Kowalski. Kowalski watched as Rico threw his doll into the storage shed, then winked at Kowalski.

Uh-oh. Better get working on that solution.
