I've noticed quite a few Baby Glorys that have pony cancer...When I was actively searching for just ONE really nice Baby Glory, all I could find were cancer spotted ones or really expensive (for her) nice ones with frizzy hair. The cancer on mine doesn't bother me as much...but it is quite sad.
Any pony clothes or hair clips I find, I typically put them on her first because I feel bad for her, as silly as that may sound...
One of my TE has cancer, too, but I only have two right now. I think Party Time is the one that has it. She also has really bad regrind, but it looks oddly cool on her. (Again, hair clips go to this girl)
