Adored by the Network: Interestingly enough, when The Hub was first starting up, Fraggle Rock was one of the shows the network was giving a big push in the marketing, probably because it was the most recognizable program on their original schedule. They even had Karen Prell film new footage as Red Fraggle for bumpers between shows. Little did they know a a certain pony show was about to steal every Hub show's thunder. The Hub stopped airing Fraggle Rock in June of 2012 (barring a 3-hour marathon on April 21, 2013 to celebrate the show's 30th anniversary). Reruns resumed on a regular basis on June 4, 2013.
The Character Died with Him: Doc's counterpart "The Captain" in the UK adaptation of the show was only featured in the first two seasons of the show because of Fulton MacKay's unfortunate death. The Captain's nephew P.K. took over the lighthouse in season 3. After P.K. left, for the final two seasons B.J. was introduced as the Captain's son.
Wembley Fraggle sounds like a younger, more innocent Rizzo the Rat — only without the Brooklyn accent. No wonder, since Steve Whitmire played both (and has even described how he had some problems making Rizzo's voice distinct from Wembley's).
