One monster (Nanu) is larger than the other (Noh), and therefore it is the little monster (Noh) to obtain food. The food consists of human flesh - preferably from children.
The monsters can turn their inside out on themselves so they look like humans. Once they have changed their appearance, it is easier to awake trust - and lure small children home to the forest.
Young children who are eaten raw.
Besides from the sketchbook studies of monster-designs, all drawings are done in red crayon, permanent marker (Pilot Drawing Pen) and Sepia, Burnt Umber and Black inks and watercolors.
