Teenage Mutant Ninja Turtles 11 + 12 (1987 TV series) Japanese VHS

No matter how much I look for volume 10, it doesn't appear as well as vol.6. Attack of the 50-Foot Irma and Leatherhead Terror of the Swamp might be included in this VHS. 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
