- Absentee Actor: Gobo is missing from such episodes as "The Great Radish Famine" and "Believe it or Not", Mokey is absent from "All Work and All Play", "Believe It or Not", "The Challenge", and "The Trash Heap Doesn't Live Here Anymore", Wembley is absent from "Junior Sells the Farm", "The Battle of the Leaking Roof", and "Red's Blue Dragon", Red is absent from "The Trash Heap Doesn't Live Here Anymore" and "The Battle of the Leaking Roof" and Boober is absent from "Capture the Moon", "All Work and All Play", "Junior Sells the Farm", "Doozer is as Doozer Does", and "The Cavern of Lost Dreams".
- In fact, it has been confirmed on the official Muppet wiki that the only character to appear in every episode is Doc (or his localized equivalent).
- Similarly, Red appears in the most episodes compared to the other main Fraggles.
- In "Fraggle Wars", none of Jerry Nelson's characters appeared. The episode explained Gobo's absence by saying he was in the Golden Grotto for the day.
- Also, Mokey is absent from the front cover of the second season DVD.
- 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 that My Little Pony: Friendship Is Magic 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 until the network became Discovery Family in October 2014.
- Channel Hop: The home video rights have bounced between several distributors throughout the years, most notably Disney (under the "Jim Henson Video" label), HIT Entertainment (with 20th Century Fox and Lionsgate handling distribution at different points), Vivendi Entertainment, and most recently Sony, who released the series on Blu-ray for its 35th anniversary.
- Likewise with the animated series, HIT included the occasional episode on compilation DVDs as bonus features. Lionsgate, Vivendi, and Sony have since released the complete animated series themselves at different points, Lionsgate doing an individual set in 2010, Vivendi including the series as a bonus feature in their release, and Sony doing both a DVD release concurrent with their release, and including all the content (13 episodes and a couple featurettes) as one big bonus feature on the ninth disc of the Blu-ray set.
- 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. ("Principal Keeper") took over the lighthouse in season 3. After P.K. left, for the final two seasons B.J. ("Bertwhistle Jr") was introduced as the new lighthouse-keeper.
- Cowboy BeBop at His Computer: The character B.J. has often been referred to as the Captain's son, even on this very wiki. In fact, he's the son of Mr. Bertwhistle, the owner of the lighthouse — "B. J." stands for "Bertwhistle Jr."
- Creator Cameo: Dave Goelz appears as the man seated next to Traveling Matt on the roller coaster in "The Thirty-Minute Work Week", mainly so that Goelz could puppeteer Matt on the coaster.
- Development Hell: Dear God, The Movie!
- Early-Bird Cameo: In Season 1, "The Great Radish Famine," Cotterpin Doozer is first seen as an unnamed baby.
- Fake Nationality: Tulsa, Oklahoma-born Jerry Nelson affects a Canadian accent as Gobo.
- International Coproduction: With the Canadian Broadcasting Corporation and Britain's Television South.
- Missing Episode: The British localization of Fraggle Rock suffered this fate, when the master tapes were junked. An effort led by fan Alex Taylor on the Missing Episodes Forum has confirmed that of the 96 episodes made, 29 still have official copies, 58 only have off-air recordings, and nine are wholly or partially lost. This, coupled with the rights problems surrounding the Television South catalogue (which has changed hands several times, and the paperwork confirming who owns what has been lost in the shuffle), is why there's never been a DVD release. Even when CITV had a day celebrating their anniversary with all the classic Children's ITV shows of the eighties, Fraggle Rock was represented by a US episode.
- Name's the Same: Mokey shares her name with a loud, psychotic version of Mickey Mouse created by Sr. Pelo.
- Out of Order: The fifth episode of the first season "The Thirty Minute Work Week" was actually the very first episode to be filmed; it was shot in March 1982. The pilot "Beginnings" was not filmed until June 1982, and was the tenth episode filmed. The reason was simple: Jim Henson wanted the puppeteers to be comfortable with their characters before doing the Origin Story. You can also see that some of the characters look slightly off in "The Thirty Minute Work Week" (most notably Sprocket, the Trash Heap, and to some extent Gobo), because several puppets underwent slight design changes after the episode was filmed.
- The Other Darrin:
- Ma Gorg was voiced by Myra Fried in the first season, with Cheryl Wagner taking over the role in the second season.
- The Storyteller Fraggle was performed by Richard Hunt in her first appearance, with Terry Angus taking over the role after that.
- Murray the minstrel was performed by Steve Whitmire in the first two seasons, but when he returned in the fifth season Gord Robertson took over the role — though the snippet of "Let Me Be Your Song" still features Steve Whitmire's vocals.
- After Jerry Nelson died, John Tartaglia took on the role of Gobo for all subsequent appearances of the character, starting with The Hub's 30th anniversary marathon in April of 2013, and an appearance at the Museum of the Moving Image the next month.note
- Short Run in Peru: HBO divided the fourth and final season into two very short seasons. The DVD release combines them both back into a single season.
- What Could Have Been: The Fraggles were supposed to be called "woozles." This name idea changed when the production team realized the woozles moniker was already used in Winnie The Pooh.
- The Wiki Rule: The Muppet Wiki, another Muppet Wiki, another Muppet Wiki, and another Muppet Wiki.
