It all starts with an idea, but you can never tell where an idea can end up. Because ideas spread, they change, they grow, they connect us with the world. And in a fast-moving world, where good news moves at the speed of time and bad news isn’t always what is seems. Because when push comes to shove, we all deserve a second chance, to score. A simple picture of an ordinary boy can be transformed. Ordinary boy can become the incredible hulk, thanks to turtles.
