Thank you everyone for the suggestions and tips!

She doesn’t show any signs of rust or mold and she doesn’t smell like mold or anything like that.

I would love to show photos but I still can’t figure out how 

They are spots and ligns, very uneven and on the tips of her hooves and ears. She came from a lot where some of the ponies had also spots and others didn’t. And there was a Sugarberry with the bright red hair in the lot so I first thought it was maybe from her?

Oh and I know these spots can be on pink ponies. I have neon spots on Galaxy and Lady Flutter but these look different. Sweet Clover‘s aren’t round like the spots on the other two.

There’s a seller from Europe that’s listing shipping to the USA for one pony is $100. $100!  One pony!  And I don’t even think it’s insured.

The cheapest shipping from Germany to the US with insurance is $52.
And there are definitely countries in Europe with more expensive shipping rates (like France for example)
So it’s not that unrealistic.
From the US to Germany I have seen prices anywhere between $20 and $70

It’s definitely not mold, it smelled like nothing  Maybe just dirt because it came off really quickly and it didn’t affect the plastic in any way.
Maybe it’s better not to think about what it could be  

My first ponies were all made in Italy.
I have to check my Posey, you said there are also different ones? Like different tulips? Didn’t know that!

Hello

I am not really into adult seaponies so I don’t have an idea of how much they are worth right now.
Could anybody tell me what price Italian Seaspray with her shell (suction cup missing) and brush and comb would be fair?

Thank you

Also, do you keep the tail weight? Or do you take it out and replace it? With what? It’s my first time cleaning an adult seapony so any advice would be awesome

Oh that’s a good one! Curious for the answers
Because I can’t decide between Polaris and Aurora!
I am not a fan of the Tootsie Pose so the other two don’t count for me

I'm sorry to hear it.

Thank you so much! I hope I found the right color of doll hair to retail her  . I always wanted her because of her bright colors

I've often wondered if Retr0Brite would work on plastic bubbles. It's for ABS plastic so maybe not.

The only thing I know would work is using a peroxide paste and then letting it sit in the sun, but that would harm the pony inside and the card.

Thank you! Yes, that is what I thought, too. Everything would harm the pony inside the bubble aswell
