I didn't mean a permanent member, just over a few episodes, if her herd is there for a few days or a week, no reason the gang may not have several adventures over those days, same with Shorty and maybe Tippy. I'd have Guido be a member of the gang, have the bullies appear more, like Mr. Thicknose. In some episodes as just 1 scene and that is it. Have Pat appear here and there, and some other characters who should be in the valley but have not been seen from in a long time.
and as I mentioned before, have not all of the gang in every episode, though I've mentioned the idea a lot before and everyone is likely bored of hearing me mention it.
