Please answer quick

I have a rat pinkie I just got it's frozen. But its hot white spots on it it doesn't look like like mold kinda looks like small drops of paint what could it be

Could it be freezerburn?

Sounds like freezer burn to me. It won't hurt the snake, but it MIGHT make the prey less appealing because sometimes they smell a little "off". If your snake has a good appetite though, he probably won't care.
