The deviant artist Q Dog2009 wisely writes;
In a sewer a long long time ago, in a New York City far far away… a group of turtles learnt the path of the force and became Jedi! to face the danger of Oroku Vader the ninja Sith Lord…. or something like that.
Hmm. Perhaps there’s an emphasis on something like that but there’s no doubting the awesome cowabunga of these Jedi Turtles.
