What kind of spot is this?

[kidcaella]

Hi everypony,


i recently received a lot of baity ponies, including an *okay* looking Sweet Stuff. I thought she had cancer spots, but upon closer inspection in bright sunlight all the larger (2-3mm) spots are surrounded by a light colored ring that is about twice the size as the spot itself. The light colored ring is actually a brighter and lighter shade of blue than her skin, and her coloring is true. It won't show up on my camera unfortunately, but has anyone got any info on this? Ive heard that cancer is brown with a darker dot in the center, but these are evenly brown. Help please!

I'm no expert, but evenly brown spots sound like some kind of stain and the light ring might suggest it was with something that stresses the material.  Don't take this as what definitely happened.  This is me just thinking through what you're saying.

If part of the spot is a lighter blue, I think it might possibly be regrind. That's just a guess though. If you could take a picture, it's much easier to identify these things by sight

Its possible that somebody tried to wash off the brown spots with something. The brown spots with light brown around them can be caused by bacteria in the plastic.

So she has a brown circle which is then surrounded by a lighter circle which at the moment is an off shade of blue?

As babystarz says pictures are going to be the best way for people to offer suggestions...but I think it still sounds like cancer its just that the discoloured area around the brown spot is still in the process of degrading so hasn't converted to brown yet. If you look at most cancer marks they tend to have a darker core and surrounding that lighter brown and surrounding that a lighter brown until you get just an off colour around the edges...kind of like like a gradient of brown to white [body colour] if that makes sense?
