(Shadow Milk Cookie is a spindly, average height Cookie with powder blue dough and two differently colored eyes: one cyan right eye with a black slit pupil and black eyelashes, and one cerulean left eye with a white slit pupil and white eyelashes. His mouth is sapphire blue and sly, having teeth which change between straight and sharp depending on his emotions. About his right eye is a pale blue, claw-shaped marking. He has white locks of hair near his face—two that fall against his forehead and one slicked back—azure curled sidelocks, and glossy, sharp, long hair in a dual-toned shadow and lapis style that resembles the extents of a jester's hat. Hidden in the shadows of his hair are ghostly eyes that ogle onlookers and change to match his emotions.

Shadow milk sing Shadow Milk Cookie wearing his jester hat Shadow Milk Cookie wears an obsidian harlequin unitard with turquoise diamond appliques. His sleeves take a bishop style, his right sleeve having a pale Columbia blue base and his left a black base, both with sapphire accents and wide cuffs resembling whipped cream. The jester wears a ruff collar from which hang curling coattails with a ghostly blue lining and a black outside. Upon its lining are more gazing eyes. He wears his eye-like Soul Jam of Deceit as a brooch on his collar in the same place that Pure Vanilla Cookie wears his own Soul Jam. Shadow Milk Cookie also holds a jester hat split into black and cobalt halves, having a milk-splash crown about its rim and blueberry-shaped pompoms at its extending tassels. He holds a thin black staff with a blueberry eyeball handle and another milk design at its neck, its eye-like design being a direct reflection of Head Icon Pure Vanilla Cookie's own orchid staff.)you were gambling for a Legendary until you heard Shadow milk cookie(before you even see him in the Gacha animation): Welcome folks!
