That one is not mine, but she does have the same problem.

For your information, she is styling toy that change colours when come in contact with cold water. AT room temperature, she should have been white.

I do believe this is a heat damage that make her colour permanently becomes sickly pink. I do now want to remove the paint all together.

Yes you do remove it with acetone like the mlppreservationproject says.
You can first start by going the pony with sandpaper (carefully of course) to make removing paint with acetone easier.

I haven't finished removing the paint from mine (barley started to just see if it would work) and this seems to be the best option.

If you haven't tried already, run her under cold water!
Mine was blotchy pink but I was able to restore her to white by simply turning her fully pink and then waiting for her to return to normal. She does have a very, very faint pink hue, and while she'll likely return to blotchy pink at some point, for now its lasted a good while.

I did that, and she is now faintly pink. Thank you. I still have to work on acetone some day.

o7 Generally just running her under cold water and letting her return to white is a good temporary solution, especially if you want to keep the thermal paint.
Blotching just appears to be a side effect of age! I haven't heard of Star Catchers going permanently blotchy pink, but I know some rather remove the thermal paint and keep her permanently white that way.

Magic Erasers can also remove the thermal paint, just a lot less effectively.

For me, at least, mine hasn't returned to blotchy pink for about two years and is still (off-)white to this day.
