I love the ninja turtle movies but I also love turtles. Real turtles are not ninjas, not appropriate pets for youngsters, and not legal to sell if their shells are less than 4 inches in diameter.
Real turtles also carry salmonella which transmits to children and adults when hands are put in mouths, eyes etc. without serious washing in between. Salmonella can be fatal to the young, elderly and vulnerable. Turtles also don't provide the type of sustained interaction that children like which often results in their being flushed, illegally dumped in a pond, or accidentally killed. Who needs that?
It also illegal in California and other places to sell animals on the street. Therefore if you see a vendor selling turtles, large or small, on the street, report it rather than buy one.
Unfortunately, history tells us that whether the featured movie animal is a Dalmatian, Chihuahua, cat or turtle the ending is always the same. Parents are exploited, pets are harmed, children are left unsatisfied with the wrong lessons learned, while the breeders/vendors laugh all the way to the bank.
Let us not be doomed to relive history. Stick with the toy turtles and enjoy the film!
