Meanwhile, back at the lair, the other Turtles had Footbot problems of their own. The pesky robots had infiltrated Donnie’s lab and were threatening to trash everything, from Donnie’s new Turtle-tech prototypes to the contraband Kraang devices they’d spent months recovering.

Mikey fended off a few Footbots and leaped on top of a rolling toolbox. He pushed off it, using it like a battering ram on wheels. He took out a few bots with finesse—until he accidentally crashed into a table of explosive chemicals.

KABOOM!

The purple flash of the explosion illuminated the room.

“Stop messin’ around!” Donnie scolded. “You’ll blow us all to Philadelphia!”

Mikey blushed. “Sorry, D!”

Casey Jones skated along the train tracks, desperately trying to catch the Transmitter Footbot before it could reach the surface. He looked over his shoulder and saw Raph struggling to keep up. “Faster, man! Move your shell!”

They both heard a rumbling sound. A subway train was barreling toward them, flying like a silver bullet out of the darkness.

Casey started to freak. If they didn’t move, they’d be pancaked for sure!

With the train right at his back, Casey slowed down and dove, tackling Raph. They rolled away from the tracks and down the gravel banks. The wind of the passing train roared around them.

Raph opened his eyes … and saw Casey Jones standing over him. They were safe.

“You okay?” Casey asked.

Raph breathed a sigh of relief. The kid had saved his life. Maybe he wasn’t such a bad guy after all. “Yeah, thanks.”

Raph exhaled and then remembered: the Transmitter Footbot!

The shifty bot had scaled the moving subway cars and climbed on top of them, hitching a high-speed ride through the tunnels.

Raph put his issues with Casey aside and shook off whatever pent-up anger he had left. He gave Casey a friendly look, as if to say, Shall we?

Understanding that Raph would hop a moving train just to smash a robo-ninja—and was inviting him along for the ride—Casey knew he’d found a new, true friend.

It was time to catch a train.
