This is a sequel to My Little Ninja Turtles part 1 and part 2.

After the turtles returned to New York and saved it from the Kraangs that invaded it, Mane 6 decided to spend a few days with their friends from another world. But what was supposed to be a simple visit and fun, ends up becoming a fight and action that none of them were waiting for, now the group needs to stop the enemy and threat that is coming.

(This story is not part of the same Equestria Ninja Girls franchise, this is my own MLP and TMNT Crossover story that I made)
