# Tentacruel (Japanese) #021 — Undone Seal

## Summary

Japanese collectors had Tentacruel in January 2004, nearly half a year before English players saw it in Hidden Legends, because Japan's PCG-era sets reliably ran ahead of the overseas releases. The Japanese Undone Seal copy is a plain rare, close up on that menacing red-eyed jellyfish face in watery blue with its wiry tentacles fanned out below. That mid-tier slot makes it an easy, affordable add for anyone gathering the Japanese run. The sold median sits at $3.48 with no copies traded in 30 days; no PSA population is on file.
