See, I told you I'd update soon! And in response to Ziptango, I am actually thinking about a new story line for a new TMNT fic, but I have to work everything out. I like to think about things before I write them. Ok, time for more story!

After walking down several sewer pipes that looked exactly the same, Donatello figured that he was seriously lost. Soon he spotted a ladder going up to a manhole that led to the outside world. He climbed it, feeling a little nervous about going topside without his father or brothers.

As he neared the top of the ladder, he heard voices and scuffling noises right up above him. He finished climbing the ladder and positioned himself so that he was hidden, but could see what was happening through the grate.

A human boy, no more than five or six was being pushed around by the neighborhood bully. "Adrian, come on, stop it!" The small boy whined.

'He sounds kind of like Mikey,' Don thought to himself. He wanted to help the boy, but knew better than to expose himself.

The bully gave the boy one final push and left. The boy lost his balance and fell face first onto the sewer grate. Suddenly the boy found two masked eyes looking back at him. He screamed and jumped back, but then cautiously made his way back to the grate.

"Hello?" He called down.

A minute later a small and timid voice answered. "Hi."

"What's your name?" The boy asked, "I'm Thom."

The same voice answered again. "My name's Donatello."

"Are you stuck down there?"

"No."

"Then why are you down there?"

There was a slight pause before Donatello answered. "I live here."

Thom blinked. "You live in a sewer?"

"Yes."

"Why?"

Another pause. "Umm...I don't know. I've lived here for a very long time."

Thom lifted the heavy grate. Donatello shrank back into the shadows.

"Come on out," Thom said.

"No."

"Why not? It's not like you're a freak or something."

Don was quiet. Finally he spoke. "Okay, but you have to promise not to laugh, and you can't tell anyone you saw me."

"I promise." Thom said solemnly.

Donatello hoisted himself up the ladder and out of the hole, blinking behind his mask at the sunlight.

"Whoa, cool!" Thom exclaimed. Don whipped around, looking for what Thom thought was cool.

"What?"

"You! You're a turtle!"

Don put his hands on his hips. "So?"

Thom shook his head. "Never mind. Wanna see my remote control car? I built it all by myself."

Don nodded, he had never seen a remote control car before. He watched, amazed as Thom controlled the little car with a button in his hand. Suddenly one of the tires popped and the car skidded to a halt.

"That's ok, I can fix it," Thom said, taking a screwdriver out of his pocket.

"What's that?" Don asked, pointing.

Thom looked down at the tool he held. "It's a screwdriver. You fix stuff with it." He motioned to Don. "Come here, look, I'll show you."

For the next half-hour, Don learned about all kinds of tools, and how to build remote control cars, and how they worked. Soon he was helping to fix Thom's car and learning to operate it.

Thom and Donatello walked down the street driving the little car together, until Don spotted the manhole that Splinter had marked in case he or one of his brothers ever got lost.

"I gotta go," Don said, a little sadly.

"Can you come play tomorrow?" Thom asked.

Donatello thought of Splinter. He would be furious when he learned that Don had gone topside by himself. "I don't think so," he said.

"Well," Thom said, "At least take this." He shoved the car into Don's hands. "I can always build another one."

Donatello thanked him and jumped down the manhole.

"I always took that car apart and rebuilt it over and over again, and then when I learned about computers, it was the same thing. But it was that boy and his car that got me interested," Donatello said, finishing his story.

He looked over to Mikey. "So I was NOT born with a screwdriver in my hand, for future reference," Don said, grinning.

Raph chuckled to himself, then listened intently for a minute. "Hey guys, I think it stopped raining. I'm outta here. I can't stay in one place with you guys for so long."

Don shrugged and started to put the original invention together again. Mikey and Leo left to get pizza.

Don finished his invention and went to his room. Opening a drawer, he took out a beat up remote control car. It had the name 'Thom' scratched on the bottom. Even though Don had never seen Thom again in his life, he silently thanked him for his inventing skills.

Don put the car back and joined his brothers in the kitchen for pizza.
