It contains the story of each of the four Turtles from volume 15. Vol.17 is about Leonardo and 18 is about Michelangelo. I liked the story about Bugman! In the Japanese version, the order of episodes has changed. Of course, these are the first Turtles cartoons I saw! At first, I rented them at a rental video shop near my house, but I wasn't satisfied with it, so my parents bought me new video tapes. When I was in kindergarten, I watched Turtles too much and never watched Japanese animations such as Anpanman or Crayon Shin-chan lol
