Story Name: Donatello's Troubles, Part One

"Would this work, D?" Asked Mikey, holding up a large mouse with buck teeth and blue eyes.

"I guess so. Here, put it in the cage." Donnie gave the cage to his brother, then picked up another mouse, this one smaller and with a larger head.

"Put me down, you miserable creation of science, or I will have to punish you when I rule the world!" The mouse yelled.

"You tell 'im, Brain! Narf!" Mikey's strange mouse giggled madly, making the turtle drop it and grab onto Raph, screaming for his life.

"Fascinating! I wonder if they came in contact with some mutagen?" Donnie wondered, picking up the dropped mouse.

"What utter nonsense! I was a laboratory mouse, and have no intention of returning to that position!" The mouse called Brain yelled.

"Easy, I'm not going to hurt you. I just want to know how you got like this." Donnie put the mice into their new cage, ready to take them to his lab.

"Pinky! Are you pondering what I'm pondering?" Asked Brain as he paced back and forth through the cage.

"I think so, Brain, but why is it called the chicken dance if it doesn't have anything to do with chickens?" Pinky asked, sitting and watching Brain pace back and forth.

"Never mind. What do the talking turtles want with us, and what is this mutagen that they speak of? Could it have some power to help us take over the world?" Brain wondered as Donnie came in with April. The red head bent down in front of the cage, examining the mice.

"They're so cute! And you guys found them in the sewers?" She wondered.

"Yeah, but that's not what I wanted to show you. Here." Donnie opened the cage door, taking out Pinky by the tail.

"Don't eat me!" He squealed, shielding himself with his paws.

"Don't worry, I'm not going to eat you. This is my friend, April." Donnie said, placing Pinky in his palm and turning him around to face her.

"Oh, she's pretty! Poink!" Pinky's face turned the color of his name, April cooing over him and ticking his nose, making him giggle.

"Pinky, you imbecile." Brain face palmed.

"So how do you think they can talk?" April asked.

"I don't know. That's what I'm working on figuring out." Donnie said, rubbing his free hand behind his neck.

"I'm sure you'll get it, D." April said as Mikey poked his head through the door.

"April, Donnie, Casey's here. He brought the Chris Bradford movies for our marathon." Mikey informed them.

"Coming!" Donnie called as he put Pinky back in his cage and closed the door.

The half asleep turtles and humans, tired of watching Chris Bradford's terrible films, were jolted awake when Donnie's intruder alarm sounded off.

Each grabbed his or her weapon, preparing to defend their home.

Three creatures beyond description ran through the lair, jumping over the turtles and running out of sight. They were soon followed be a fat security guard with a butterfly net, who didn't give the turtles so much as a second glance.

"That was just... Strange." Leo said, lowering his Katana.

"You live with Mikey." Raph reminded him as Donnie headed back to his lab.

"No!" He yelled, running back out into the main room.

"What is it?" Asked Casey.

"My new mice and a can of mutagen are gone!" Donnie panted.

"You mean they're loose!?" Casey shouted.

"Kinda yeah. Maybe those lunatics from before had something to do with it." Donnie shrugged.

"Fan out. Casey, Raph and I will go topside to search. April, Donnie and Mikey will cover the sewers. They can't be far!" Leo ordered.

"Why would someone want to steal some lab mice and mutagen?" Raph wondered, throwing a bean bag aside and following Leo and Casey.

"I don't know. Maybe they want even more mutants roaming around New York." April said as she bumped into Master Splinter. "Oops. Sorry, Sensei." She added meekly.

"What is all this about?" The Sensei wondered.

"Sorry, Master Splinter, fill ya in later!" Mikey said, grabbing his skate board and hit the pipes, Donnie and April not far behind.

It's not done yet, part two will happen soon! I promise! Yes, it is a tribute to Rob Paulsen. :) Without him, your childhoods would suck. NARF!
