Title: How to be a ninja
Description: I am Master Splinter. For many years now, I have been sensei to the greatest team of warriors I have ever known: the Ninja Turtles. Being their teacher in these ancient skills and guiding them as they have come of age has been the greatest honor of my life. If my great students, the Ninja Turtles, should ever be defeated, other worthy heroes must rise up to defend the world. As you read these lessons, you may discover that it is you who are worthy.  Do YOU have what it takes to be a hero?
