'Presto Change-O' is a good episode. Preston gain real magic powers and it will only work if he used them to help people. The boss villain came to Earth to fight the rangers, but chicken out, when he learn that he could lose to them. As a result, he send a turtle alien to fight them instead. While the alien managed to get 3 Ninja Power Stars, but he lose them and get destroyed. Then, he became a giant and get destroyed again. I can't wait for the next episode.
