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.
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.
