It's an illustrious Model of "Mallory/Mallary/Sumimomo" from Animal crossing/Doubutsu no Mori

Trigger word :

Mallory-AC, duck, purple skin, feather, black eyes, beige eyelids, orange beak, orange palmate legs, white shirt with blue stripe, small dark green hair on head

You can add : Solo, 1female.

If you have some problem with the generation you can try to replace "Duck" By "Bird" or just remove it and try to change "small dark green hair on head" with something else more precise like "Small tuft of dark green hair on forehead between ears"
