While Gobo is in Outer Space looking for Matt's postcard, Doc decides to board up the hole in the wall leading to Fraggle Rock. While Gobo dodges Doc and Sprocket, his friends launch a rescue mission. Mokey and Boober work on breaking the boards, while Red and Wembley try to rescue him by following Marjory the Trash Heap's advice: "Don't cry over spilt milk."
While this is the tenth episode of the series, it was recorded in April 14, 1982 as the second. It is also the shortest episode of the series. Due to its length, it's (surprisingly) the only episode airing on The Hub to feature the full version of the opening sequence.
