Style: thick dark-brown outlines, flat cel shading with one shadow tone, matching the base exactly.

Pose: three-quarter view turned to the viewer's left at eye level, same perspective as the base; never show a hat's underside or lining.

Flavour: gangster monkeys. Draw 6 slouchy or cuffed knit beanies (black, charcoal, red, navy, olive, mustard; ribbed cuff, some with fold-over or pom). Draw 6 backwards baseball caps in wool, twill or leather (black, white, red, royal blue, camo, gold); the brim points toward the viewer's right, behind the head, foreshortened, with the adjustable strap and opening arc facing the viewer's left over the forehead.

Placement: the hat covers the fur crest (crest peak x≈515, y=152) and the whole upper cranium, with its top reaching about y=110-150. The lower edge wraps the head from x≈350 to x≈690: it sits at y≈335-355 over the brow on the left/front and may dip to y≈365 near the right ear. Its lowest pixel must stay between y=330 and y=370, never below the brow ridge (y≈335 at the eyes, eye line y=422).

Centre the hat on x=470. The hat sits between the ears (left ear x 308-365, right ear x 665-718) and may overlap only their tops above y=360. Backwards-cap brims may extend right to x≈800.

No floating gap above the crown.
