Although it was designed with Petz in mind, I found that this program, made by Brynn (great programmer and hexer from the PC), works very well for making random freckles on Babyz. Might not be great if you'd like to control the placement of freckles, but good for generating unique and random birthmarks.
Paintballz in Babyz are identical to those in Petz, so all you have to do is type in numbers that correspond to Babyz colors and ball numbers. So if you want freckles on the cheeks, you might enter this: # of Paintballs: 10 Color: See Freckle Hexing thread for colors Min size: 5 Max size: 10 Texture: -1 Fuzz: 0 Ball Numbers: 8 9
Hit "Generate" and copy + paste code above the rosies under [Paintballz]
