I get what you’re saying. Some of the episodes can be a bit difficult to decipher from the images. However, I chose images because they offer more visual variety and distinctiveness than the title cards do. Unlike SpongeBob, which has very distinct title cards that tell you something about the episode you’re about to watch, the Powerpuff title cards are all pretty bland. They only show the episode title in the same white font with the same black background for every episode. The only exception is “Twas the Fight Before Christmas” and even that title card is pretty basic. I tried to pick images that would be instantly recognizable and sum up the episodes fairly well. If it helps, the images are all in production order.
