The air inside the dimly lit laboratory was cold and sterile, the faint hum of machinery filling the silence. The Turtles moved cautiously, their footsteps muffled against the sleek tiled floor.

Leo: “Keep it quiet, Mikey”

Leo whispered, his katana at the ready as he led the group through the maze of equipment

Leo: “We’re not here to start a fight.”

Donnie reached out and clamped a hand over Mikey’s mouth, silencing him

Donnie: “As much as I’d love to hear the end of that sentence, we’re in enemy territory,”

Donnie hissed, his bo staff pointed toward a surveillance camera overhead

Donnie: “Security’s tight. One wrong move, and we’re toast.”

Raph, bringing up the rear with his sais, scowled

Raph: “Yeah, well, let’s hope you can keep us from getting toasted, Brainiac.”

Donnie glared but pulled out a small device, fiddling with it as he muttered

Donnie: “Just give me a sec to loop the cameras…”

Leo signaled for silence, and the group huddled behind a massive workstation, its surface littered with glowing vials and half-assembled machinery. In the center of the lab, a glass chamber glowed ominously, filled with swirling green liquid.

Mikey: "What do you think they’re cooking up in there?"

Mikey whispered, his voice tinged with awe

Donnie: “Nothing good”

Raph growled

Raph: "Let’s smash it and get outta here."

Leo: "Not until we know what we’re dealing with

Leo said firmly

Leo: "Donnie?"

Donnie: "Working on it"
