RMS Mystery Squishy Dumpling Seashell Series — photo 1 — Image via eBay

This is an RMS mystery dumpling squishy from their Seashell Series collection, meaning the exact character inside is unknown until opened—part of the appeal for collectors who enjoy the surprise element. The dumplings are small, soft, and typically feature ocean-themed characters in pastel or iridescent finishes. Uncommon rarity means it's less frequently restocked than standard releases, making it moderately harder to source and more likely to trade above retail on resale.
