Writers are important for this and many projects as it's the foundation of any story. All I ask is that you have an understanding of the TMNT franchise or even know lots about them. Not be afraid to throw out ideas and be able to work in a range that helps animators and actors alike!!!

   You will need access to a software/app called STARC or rather Story Architect. It's free and prefered method in my projects especially for the tools provided!
