Splinter, Young Michelangelo and others in “Unfinished Business”

Join me, my sons. For tonight I have something special to share with you.

Ooh. Presents, Sensei?

Shh. Quiet, Mikey.

Cool. I love story time.

I wanna know more about Japan, Master Splinter.

Not tonight, Leonardo. I have told you before of how we all came to be together. But I have not told you everything. After finding you in a pet store one afternoon I bumped into a mysterious stranger. I followed him, only to have my curiosity...undermined. In the struggle that followed we were all exposed to a strange substance...changing us forever, turning us into very unique beings. Our journey together has not been an easy one. But it could not have happened without fate, courage, and great purpose. The world we live in is very dangerous. We have many enemies in the city above. My duty is to teach you all I know. One day, you will need to choose your own destiny. But tonight, I want to tell you the rest of our story.
