Possum-bodied, monkey-armed, human-handed, mole-faced, cat-sized creatures with red eyes and numerous tentacles sprouting from around their mouths. They are horrifying creatures that lurk in the shadowy mouldering places of the world, drawn to areas where the boundaries between planes and realities are thin. They are abnormally intelligent and tend to create cults of foul vermin and rodents around them. They like to eat flesh and steal babies. Their bites cause bleed damage and can affect incorporeal creatures as if they were ghost-touched weapons. They speak Aklo.

One was encountered (and defeated) by the party in the boiler room on the first day of the adventure.

Zoogs were referenced in Monuments of the Forest, one of the books in Lowls' footlocker, as living in the Enchanted Wood in the Dreamlands.

In Chapter 107, Dora recalled that Zoogs in the Enchanted Wood are generally much healthier and civilized than the one the party encountered in Briarstone. High in the order of community, but low on the food chain. They eat feline flesh.

In Chapter 108, the party palavered with an insanity of Zoogs led by Burukur.
