Skullpelts were a species of predator that hunted in lullabee groves in the Deepwoods. To people entranced by the trees in lullabee groves, skullpelts would look like someone they would be drawn to, so they would approach and be easy, defenceless prey. However, this appearance was only an illusion; skullpelts could not change their form. The illusion was also imperfect; the illusionary person would always seem to be wearing blue fur clothing. Skullpelts actually had blue fur, along with taut, scaly skin, orange, scaly hands and feet with three digits, bulging yellow eyes, yellow claws, and rows of hooked teeth.
