I haven't watched them in a while, but from what I remember I enjoyed Seasons 8 and 10 the most. I wouldn't mind seeing something similar for a new series. Personally, I really like "Mobster from Dimension X." It's a fun episode. "Turtle Trek" and the "The Day the Earth Disappeared" are also pretty good. The cover of "Transdimensional Teenage Mutant Ninja Turtles" by Palladium Books looks very similar to what happens in the latter episode.
