Marjory the Trash Heap is a large, matronly, sentient compost heap from Fraggle Rock. According to her rat-like companions Philo and Gunge, who serve as her shills, the Trash Heap knows all and sees all. In fact Marjory is all: “I’m orange peel, I’m coffee grounds, I’m wisdom!” She serves as an oracle to the Fraggles, dispensing advice and wise sayings, and the Fraggles stand in awe and reverence of her. However, the trash heap lives outside the caves of Fraggle Rock, residing in a corner of the Gorgs’ Garden. This makes any journey to seek her wisdom perilous, as the Fraggles must sneak past Junior Gorg.
