This is a mystery dumpling squishy from RMS in the uncommon Seashell Series variant, featuring ocean-themed colors and designs within the brand's collectible blind-box format. The uncommon rarity means the Seashell Series was produced in limited quantities, making specific variants harder to obtain and more likely to trade above retail on secondary markets. Collectors of RMS mystery dumplings and those chasing complete series sets would prioritize this variant.
