With the advanced CG in today's age, I find it amusing how they still make crappy looking cartoons. Even when I was a kid the cartoons looked better.Yeah,I actually saw that episode and I think it was Maul's brother Savaj who found him and attached the robotic lower half.
I thought you might have been referring to one of the novels...I don't really get into the cartoon because I don't care for the artwork,I feel that a Star Wars cartoon deserves more realistic looking artwork
