We have no details, such as colors or male to female ratios. But speculating on what colors Iwako might use can be fun. We would of course, expect Iwako to represent the other ethnic groups. We were thinking of a lime green baby with bright orange hair and a blue bottle. Or a purple baby with red hair and a black bottle. Or a blue baby with yellow hair and a green bottle. With so many colors you could create your own psycho baby.
