Boober tells Wembley and Gobo that he's making a radish gumbo. However, he has a problem. His kitchen has every vegetable but a radish, so he makes rutabaga gumbo with dried greaseberries and skunk cabbage. He is also doing laundry, but somebody put yeast in his Rock Soap. Boober mixes the soup and wash water, and unwittingly creates a substance that turns Fraggles invisible. The Fraggles use the invisibility soup to raid the Gorgs' garden the same time when Junior Gorg helping Ma Gorg and Pa Gorg with their spring cleaning. but Boober worries that the new mixure is too good to be true.

Meanwhile, Doc and Sprocket end up doing some spring cleaning in the workshop until another plumbing problem happens.

Fraggle Facts

• The Gorgs live for a very long time. Pa Gorg has been saying that he's going to fix the same clock for 104 years.

Goofs

• Watch for a curious shot in this episode -- during the rock quake, Wembley, Red and the rest of the Fraggles shake along with the set. Boober shakes along too, but after a few shots, he, along with Gobo, stands perfectly still and apparently unaffected by the quake.
• Wembley uses a Doozer stick to try and fish the skunk cabbage out of the gumbo, which makes the stick invisible, but then it becomes an ordinary stick. Also, Red calls the stick a ladle after Mokey becomes invisible.
