Thanks to Zap2it, we finally have the title of the final missing episode, which will be comprised of two 11-minute shorts. Zap2it lists "Pizza O'Possum's" and "The Curse of Half-Beard's Booty" as the final unreleased episode, which is actually intended to be the third-to-last episode according to head writer Jon Colton Barry, with "Professor Huh? Parts 1 and 6 3/4" being the intended two-part series finale. Zap2it also gives us a description for this episode, "Shaggy drags the gang to a childhood arcade where he's determined to finally collect enough tickets to win the prize he's wanted since he was a boy." However, the description is vague enough that it could be for either one of the 11-minute shorts.
One thing which is probably important that I note, however, is that the head writer, Jon Colton Barry, has revealed that "The characters and comedy are nothing like what we had established for two years." That being said, Jon has also stated that he had "nothing to do with the first 11 min and barely anything to do with the second." This, and some other comments he has made on the ScoobyAddicts forum, allude to the fact that the episodes are simply experimental and have quite a different feel than we are used to for the show.
In addition, you may notice in the Zap2it page which I linked to, that an airdate of November 13th is given. Unfortunately, Zap2it has been very poorly reporting on the dates that the episodes air, to the point where in fact none of the season 2 airdates they listed are factually correct, and it's essentially become a completely free-for-all as to if the dates they list are for other countries, or completely made up. While everyone is welcome to their own opinions and interpretations of what this date means, my personal thoughts are to take the November 13 date with a grain of salt, seeing as none of Season 2 dates listed are correct, and many of the season 1 dates aren't correct either. However, it is possible that the November 13 date could be for Australia, which has aired every episode other than this one.
I'll try to keep you guys up to date on any info regarding when this final unreleased episode will air. In the meantime, I'll be checking my international TV guide sources on a regular basis to see if the episodes are airing there at all. But in case you all want to do a bit of investigating yourselves, these are the sources I've been getting most of my information at regarding the international air dates. TV Guide UK lists the entire Boomerang schedule for seven days out, and this Foxtel spreadsheet (which I had to do quite a bit of searching to find!) lists every single Be Cool, Scooby-Doo episode airing for the next two weeks in the entire country of Australia.
Stay tuned for more info! :)
