This was a favorite episode of mine. The story line is that Moki thinks that eating the Doozers work is wrong and she believes and wants all the Fraggles to stop eating the Doozers buildings. She starts following her friends around trying to make sure they don't eat the Doozers work, which starts causing problems for the Doozers. First, the Doozer buildings start taking over Fraggle Rock and Two, Moki overhears some Doozers making plans to move from Fraggle Rock due to the Fraggles not eating their buildings. The Doozers talk about how if the Fraggles don't eat the buildings then they can't build more and eventually they will die. Meanwhile, in outer space, Uncle Matt sees humans wearing construction hats and think they are Doozers. He decides to taste their buildings and leaves disappointed.
