Rottmnt-After Kraang
As the days went by, the turtles became more and more isolated, afraid to leave their lair for fear of being discovered by the Kraang. They spent most of their time training and honing their ninja skills, leaving little time for their human friend. You tried to reach out to them, but they always seemed distant and preoccupied. You couldn't blame them, of course. The invasion had changed everything, and they were doing their best to protect themselves and their home.
