Chapter one
"Casey Jones...has arrived!" A voice boomed, echoing off the tunnel walls and into the lair. Sounds of crashing accompanied the entrance of the young man. Everyone cringed as a loud shriek escaped Mikey's mouth, ducking as a hockey puck flew past his head and collided with a street sign that was mounted on the wall. The loud clang hung in the air until Mikey got up from his crouch and pointed angrily at Casey.
"Casey, we told you, no roller blades in the lair!" Mikey shouted. He glanced behind him, and his eyes widened in surprise. He stared forlornly at the dented piece of wall art and yelled "and stop breaking our things!"
Casey stomped into the room indignantly. "Aww, Mikey I was just messing around!" he said, clearly annoyed that he was being lectured by the prankster himself.
"Michalangelo is right," said Splinter calmly. "Our belongings do tend to be severely damaged after your visits, Mr. Jones."
"Casey, you are such a dork!" April said, looking back over the couch cushions where she was sitting with Leo. Her laptop was between the two of them, and had various building schematics spread across the screen.
A stream of protests came out of his mouth as he began to make his way to the beanbag chair across from the television. Suddenly, his shoe caught on a seam in the flooring, and he crashed down the small staircase with a yelp.
Mikey let out another horrified scream as Casey's elbow crunched into a box of VCR tapes by the couch.
Frantically, Mikey pushed Casey's sprawled form away from the box and picked up a shard of the black plastic. With a shaking hand, he brought the shard up to his face. "Y-you...MONSTER!!!" Mikey picked up the box and sprinted away, his cries of "DONNIE!!! EMERGENCYYY!!!" fading down the hallway.
Raph poked his head out from the garage, where he was working on his bike. "What happened now?", he asked sarcastically. His eyes widened at the sight of Casey, sprawled face down on the small staircase, with shattered black plastic by his arm.
Fighting a grin, Raph coughed briefly to stifle a laugh. "Oookaay...hey Case, you alright?" Casey answered with a groan and held a thumbs up over his head briefly.
Splinter sent Raph a pointed look and nodded his head towards the entrance of the lair. "Hey Casey, let's go topside, get some air." Casey nodded his head as he picked himself up from the floor and headed for the turnstiles. Raph grabbed his skateboard and jogged after his friend.

Wheels skittered against gravel as the pair raced through the tunnels. The sound suddenly grew louder, and Raph looked back in confusion.
"Heh, hey guys..." Mikey called out over the sound of scraping wheels coming to a stop. "I heard you were going out, and I didn't really want to stay in the lair, so..."
"It's cool man," said Casey. He dropped his gaze to the floor. "Look, I'm really sorry about breaking your movies."
"Oh, right!" Mikey exclaimed cheerfully. Casey shot a very puzzled look at Raph, who rolled his eyes and shrugged. "It's cool! Donnie said that the film tape stuff wasn't damaged, and he could just put it inside a different case."
"Oh." Casey grinned, and turned to face the empty tunnel. "Race you guys to the surface!" With that, he shot off towards the nearest exit. "Hey!" Raph and Mikey yelled indignantly, chasing quickly after him.
When he was still a good 20 feet away from the exit, faint rumbling reached Casey's ears. Casey halted unexpectedly, rollerblades shrieking in protest. He put his hand up to signal the others to do the same. Raph and Mikey immediately got in a defensive stance. "What is it?" Raph hissed sharply.
Small cracking sounds came from the top of the tunnel, and they all looked up as dust fell from the cracks and onto their faces. Tiny chunks of cement began falling around them as realization hit. A larger section slammed down near Mikey's foot, crushing the skateboard alongside it.
"Get out of the way, it's gonna fall!" The three sprinted towards the manhole cover at the end of the tunnel as the loud rumbling began, sending huge sections of concrete to collapse around them.
