The creators of Fraggle Rock ran a professional production, but the occasional goof did manage to make it onscreen. * When The Fraggles pop up behind the Doozers, Steve's head is seen, and Karen Prell's arm is seen. * When Wembley runs to the Fraggle pond, Steve Whitmire's arm is seen. * Starting with "We Love You, Wembley", Gobo and Ma Gorg were redesigned, although the original puppets remain intact during the opening. The original Gobo puppet also remains intact during the closing. * When Red, Mokey, Gobo, and Wembley say "Down in Fraggle Rock" when the title is shown, you can only hear Gobo and Wembley's voices. * Before the song Hip Hip Hooray, during a pan shot, a couple of performers' heads can be seen in the background, making their way to Fraggle Pond set. *
