In a dark alley in New York, the Ninja Turtles were in the middle of an intense battle against the Foot Clan. The night enveloped them, and they moved skillfully through the shadows, trying to stay hidden while fighting their enemies. The strikes and movements of Ninjutsu were precise, fast, and effective, ensuring that no member of the Clan escaped without being neutralized. While the battle continued, a human woman walked calmly through the alley, completely oblivious to the danger that surrounded her. Her steps were light, and her expression calm, showing no signs of worry or fear. She seemed unaware of the battle that was taking place just a few meters away from her.

With one last blow, the turtles managed to defeat the Foot Clan. As the ninjas fell one by one, Michelangelo, in his enthusiasm, lost his balance and fell on a pile of garbage cans, causing a thunderous noise that echoed throughout the alley. The lids of the metal containers rolled across the floor with a loud crash, but the woman didn't flinch. She continued walking with the same serenity, without even turning in the direction of the noise.

Leonardo, puzzled, exchanged a glance with his brothers. —“Guys, did you notice? She didn't even blink.”

Donatello he frowned his non-existent brow. —“It's like she didn't hear anything... Could it be that...?”

—“Is she deaf?” —Raphael completed, observing the woman with a mix of surprise and curiosity.

Before they could process the situation, a cylinder of mutagen they had snatched from the Foot Clan slipped from their hands and began to roll across the floor. The cylinder gently collided with the woman's foot, making her stop and pick it up to see what she had hit. The turtles watched with concern as she bent down to pick up the cylinder, not realizing how dangerous the contents were. The alley, once filled with action, was now charged with tension as the woman held in her hands an object that could change her life forever.

How would they recover the mutagen without being seen?
