Drawcia Soul appeared in 2005 video game called Kirby: Canvas Curse. Drawcia Soul is the undead form Drawcia assumes during her second phase as the final boss of Kirby: Canvas Curse.
Drawcia Soul, the mad witch's second form, is stylized to look like a big blob of paint. She has a dripping, gaping yellow mouth, with five yellow eyes along the top of her head; these seem to be a modified version of the yellow bodily markings Drawcia had previously been hiding under her cloak, and makes Drawcia Soul look vaguely similar to a painter's palette. Her paint-like body constantly swirls about, changing color, but starts out pink and is portrayed that way in official artwork.
Drawcia's default form shown in the ending - the 'unknown painting' - initially appears to be just an abstract arrangement of colors, but upon closer inspection is shown to have similar elements to both forms of Drawcia: the figure depicted in the painting appears to be a circular blob of colors like Drawcia Soul, and one can vaguely see the sorceress form's face in the painting.
