Amy Sue Grue was an Antharian Grue living in the underground tunnels
beneath Festeron. Her parents named her “Amy Sue” because they thought
it was cute. Like most grues of the local region, her nest (a.k.a.
apartment) was equipped with a sofa and a Frobozz Magic Grue
Refrigerator, as well as the usual lining of rusty swords of elvish
workmanship, piles of bones, and other debris.
Unlike nearly all grues, Amy Sue Grue was not only fluent in the
tongues of men, but also quite hospitable towards them, as long as they
refrained from switching on any light source (for she intended to
proudly uphold the grueish tradition “No human being has ever seen a
grue and lived.”). The tone of her voice was gravelly.
After a period of mating, Amy Sue Grue had been confined to her lair to
care for her newborn baby. Being a single mother, she had found it very
hard to get out and do things. It was even more seldom that she had
opportunities to talk, and she had had lots of questions about the
outside world. Finding a sitter for the child was impossible.
Simon the Postman, having been warning to keep all lights turned off
beforehand, befriended Amy Sue Grue. She aided him by directing him
through the underground tunnels into The Festeron Palace in order to
discover the location of Gladys’ hideout. Additionally, this mother
grue devoured the Boot Patrol (the human replacement) when they broke
the rules and pursued Simon and Mr. Sneed into the underground. Brad
MacGuffin was amongst those who were consumed. To date, this the
only reported friendly encounter with a grue, as well as the only known
grue able to speak human.
