In the midst of a fierce battle, the Teenage Mutant Ninja Turtles were engaged in a chaotic fight against their old foes, the Krang and the Foot Clan. The air was filled with the sounds of clashing weapons as Michelangelo, Donatello, Leonardo, and Raphael fought valiantly, their skills on full display. After a tough struggle, they finally overpowered the villains, delivering decisive blows that sent the Krang sprawling.

As the dust settled, a strange noise disrupted the silence—a low hum that quickly escalated into a roar. One of the remaining Krang bots activated a device, and a swirling, violet triangular portal opened, crackling with energy.

Before the Turtles could react, four figures resembling them tumbled out, landing awkwardly on the cold, damp ground of a dark alleyway on a chilly winter evening. The clock nearby read 8:30 PM, casting a dim glow over the scene.

But as the last figure emerged from the portal, a blinding flash enveloped them. When the light faded, the battle-hardened Turtles had transformed into four small, human babies—wide-eyed and utterly confused. Each wore beanies matching their original colors: orange, blue, red, and purple, but now they could do little more than squirm and babble helplessly, grappling with the reality of their new predicament.
