The meaning of this painting is obvious:
A spawnling, under the influence of the Skeleton of Urban Turpitude, watches a Krepp imp pursuing a Cuspid Mole. She waits patiently, brandishing a Cabin Worm, for the mole to make its appearance, so that she can steal it from the imp. The Skeleton has impaled one of her clabber-ears and has accessed her menta-gland, and so is in temporary control of the spawnling's will. Although aware (and disturbed) by the situation, she is focused on her plan to take the hard won rodent from the determined little fellow at the moment of his triumph.
Grates to She Walks Softly
