From Pembrick’s Creaturepedia:
“The mighty male bomnubble creeps the slopes of the Stony Mountains. He is long of tooth, strong of odor, and sneaky of walk. The bomnubble typically makes its home in caves, and seems to prefer caves on the south slopes of any particular mountain. The bomnubble’s diet consists mainly of wolves, humans, and berries, and his belly is notorious for its hunger and hairiness. Nothing whatsoever is known of the female bomnubble.
“This picture was drawn whilst hanging from a tree near a cave in the western range of the Stony Mountains. I named this one ‘Alusius’, after my dog Truby.”
