What if the Teenage Mutant Ninja Turtles found themselves in a fierce battle alongside their allies against a powerful new enemy, Skilo, a magic user capable of bending reality? During the confrontation, Skilo unleashed a spell that enveloped Leonardo, Raphael, Donatello, and Michelangelo in a blinding flash of light. When it faded, they realized they had been teleported to a hidden dimension beneath the cities of the world: the magical Kingdom of Luton.

In this strange realm, the Turtles discovered they were no longer the fierce warriors they once were; instead, they had been transformed into human children. Leonardo was now a bewildered five-year-old, Raphael a curious four-year-old, while Donatello and Michelangelo were adorable two-year-olds, innocent and wide-eyed.

Abandoned in a dim alleyway, surrounded by towering buildings and vibrant murals, the young Turtles tried to understand their situation. They felt vulnerable and frightened, lacking the skills that had once defined them. As they huddled together, unsure of how to navigate this astonishing yet terrifying world, a low, guttural voice echoed through the alley.

"What do we have here?" a creature sneered, its laughter sending chills down their spines. "Oh, a group of lost little lambs. How intriguing. What could you be doing here, all alone?"
