This trend the show is in, with the lack of Wilt, Ed, and Coco, has got me thinking. I'm not so sure it's because they're trying to focus less on them, although I can understand when there's a few episodes where they're not focused on as much. It could be something out of their control. For instance, I think we all know there's more to a cartoon character than drawing it, animating it, and giving it a voice. Someone needs to write what it's going to do, what it's going to say, exactly how it does things and when, and someone needs to supervise the whole thing so everything goes smoothly with the rest of the show. It's easier said than done. And although they're not credited, I'm sure the Foster's characters each have three or four people solely in charge of them. It's also possible one person is responsible for more than one character, like one animation supervisor is responsible for the animation of two or three characters, not just one. I'm not wanting to blame anyone of course, being a loyal fan and I support the whole crew, so I'm wondering if one of these people had to take a personal leave around the time the episodes were being written. And in wanting to save time and money, and not wanting to pass the job onto anyone else (who surely has enough on their plate as it is), those characters simply weren't written into the episodes as much as usual, or at all, as is Coco's case. Perhaps this person carried most of the responsibility for Coco's character, and maybe also had some responsibilities for Wilt and Ed. Thus we don't see Coco at all for a few eppies, and only small cameos of Wilt and Ed.
Just a theory.
