Freshwater Lagoona Accessories?

Hey guys! I recently found a Freshwater Lagoona being sold for not a million dollars but shes missing a leg fin, her necklace, and possibly an earring. Ive been searching all over to find someone selling her accessories but havent been able to find anyone 😢.

I was wondering if theres maybe some online shops that have her accessories for her or MH dolls in general as some of my childhood dolls are also missing small accessories.
