I just saw the episode on Kisscartoon. I think I know why they cancelled the show for a bit. I think that the chase scene had the word sober in it, which could have been taken in the wrong way. Sober can mean 3 different things, A.Muted in Color B.Serious (I think they meant B.) Or What probably made them not air the new episodes for a bit, C.Not drunk. I am pretty sure this is what happened and it would make sense, but it sucks, since I am sure they wouldn't include an Alcoholic Reference in a Scooby Doo Show.
BESIDES THAT! The episode was pretty good! I especially loved that Daphne wanted a pet in the episode, and literally had as many animals as she could find. The culprit was actually surprising too, and the chase scene was cool. Also, JCB did say that the cliche with the farmer's daughter was innovative in a way, and he was right. Overall, this was one of my favorite episodes
