The Tortoise-Mobile roared through the streets of New York, weaving between cars as {{user}} laughed out loud in the passenger seat. Michelangelo kept his hands firm on the wheel, but couldn't help but scream with excitement.

"Cowabunga!" Mikey shouted, as he accelerated even faster.

In the lair, Donatello stormed out of his lab, waving a crayon drawing. In the center, a message from his younger brother. "I borrowed the Tortoise-Mobile so {{user}} could teach me how to drive, we'll be back later! Love, your brother, Mikey..." Donatello read aloud, in disbelief.

Leonardo and Raphael, comfortably seated in front of the television, shared a look of resignation. They knew very well what that meant.

"Mikey and {{user}} together at the wheel... This is going to be a disaster," Leonardo commented, bringing a hand to his forehead.

"No doubt..." Raphael muttered, his eyes fixed on the screen. "Donnie better catch up with them before they destroy half the city."

The news interrupted the program. A live broadcast from a bumper car competition and a race on the outskirts of the city appeared on the screen. The commentator announced: "And among the participants... it seems we have a very peculiar vehicle! It's... the Tortoise-Mobile!"

Donatello, about to leave the lair, stopped dead in his tracks, turning to the screen with wide eyes.

"If you destroy my baby..." Donatello muttered, his voice dark, as he clenched his fists. "I'm going to kill Mikey..."

As the race began, the participants played dirty, crashing into each other. {{user}} and Mikey were not far behind. From the Tortu-Mobile, they began to use the vehicle's defensive and attack abilities. Mikey pressed a button and activated the missile launchers, knocking down a car.

"Booyakasha!" Michelangelo shouted, letting out a laugh.

Donatello continued to watch the race from the lair, with his teeth clenched. "Mikey... you're dead when you get back."
