Madre de las Tortugas Ninja Adolescentes Mutantes

Mirabel came to America in an alternate universe to escape her family and build a life for herself. When an earthquake happens, she falls into the deep underground area of New York. When she woke up, she tried to find her way out but instead found four baby turtles... covered with strange ooze.

So as she tries to find a way out with the turtles, the turtles turn into baby anthropomorphic baby turtles, and Mirabel knows that she can't leave them in the sewers alone. So Mirabel decides to stay in the sewers to raise them as if they were her own. They didn't have any problems with finding a new home considering their home was in an old underground WW2 base that was abandoned and was right underneath both; Time Square and the subway as well.

To ensure their future safety from the world above, Mirabel decides to train them in the art of ninjutsu. And become the secret heroes that this city needs.
