Fraggle Rock
Air Date June 3, 1983
Written by Sugith Varughese
Director George Bloomfield

As usual, Wembley has a tough decision to make: to compete in Red's Splash-a-Thon, or accompany Gobo on his trip.

The Beast of Blue Rock lies within...the blue rock!

Fed up with Wembley's wembling, Gobo makes the terrifying journey to face the dreaded Beast of Blue Rock alone. But Gobo forgets his pickax, so Wembley has to go after him.

Meanwhile, Doc tends to Sprocket when he falls sick and plans to take him to the veterinarian.

Fraggle Facts

  • Blue Rock is a magical place. It's visible only two days after the Doozer Equinox, and then disappears for a year.
  • Marjory the Trash Heap shows her magical abilities here, appearing to Wembley and Gobo at Blue Rock and teleporting them home again.
  • The Beast of Blue Rock is not a physical creature but fear. As Marjory says: while the beast will return, with the help of friends it can be defeated -- as it was by Wembley and Gobo at Blue Rock.
  • Marjory also explains that she was the one who made up the rumor of the Beast of Blue Rock, expressing surprise that the old rumors kept Fraggles away for centuries.


  • Large Marvin, the fattest Fraggle in the world, debuts in this episode.
  • On writing this episode, Sugith Varughese recalls that he "pitched an idea to Jerry and Jocelyn that eventually became Beast of Bluerock. That was my first episode. But you have to understand, I don’t think I can remember any of my ideas actually becoming the script. I’d go in with a well-worked out idea and then Jerry and Jocelyn and Larry would contribute ideas and by the time I came out of the room, it was a whole new, better idea—but one that I could now write. And that happened every episode."[1]
