Not enough Trash Heap

[AmazingMumford]

Did you ever notice that during Seasons 2 and 3 of Fraggle Rock the Trashheap wasn't used very much at all? I never really noticed this until I read the detailed episode guides. She was in a fair amount of episodes in Season 1, I think 13 all together, and in the last season she was in 7 episodes, but I think between seasons 2 and 3 she was only in a total of 3 episodes. I always wondered why she wasn't seen more regulary during seasons 2 and 3. I always thought Phillo and Gunge should have had a more regular role on the show.
