Thanks Icebot and pannoni1,
I knew the Turtles were obviously familiar with Dimension X WAY before actually entering it (ever since "Hot Rodding Teenagers from Dimension X"), but I thought maybe there would have been a phrase or small discussion among them first entering it ("Shredder's Mom" then according to Icebot). Similar to how people know a lot about New York City, Los Angeles or Disney World but when they first arrive its still a fascinating experience.
I guess I'm just looking too deep into this cartoon. LOL
