The Mystery Dumpling Sea Shell Edition is a blind-box squishy from RMS featuring ocean-themed designs within the collectible dumpling line, where each box contains an unknown variant. The squishies are soft, squishy silicone with a smooth finish typical of the Mystery Dumpling brand. Marked as rare, this edition is harder to find than standard Mystery Dumpling releases, and the blind-box nature combined with limited availability means sealed boxes and specific variants trade above retail. Collectors pursuing the Mystery Dumpling line actively hunt for this sea shell edition to complete themed sub-collections.
