We are interested in bringing the series back, and need a glossy "hero image" to help market the show.
This would feature the title, "The Fuplers!" combined with each of the four characters.
The characters can be illustrated, or they can be pulled as screen-grabs from one of the old episodes (several images attached, plus YouTube playlist below). Note that most of the episodes are low res, so this could pose a challenge. If you don't like any of the attached images, I suggest pulling from the later episodes which are in HD. Also challenging is that you only can see their upper bodies. Time to get creative!
UPDATE: Please note, this graphic is a title first and foremost, so the text should be the center of focus in the illustration. The characters can be secondary. Thanks!
