# Grumpig (Japanese) #179 — SI: Start Deck 100

## Summary

Grumpig is a plain holo-free slot in the Japanese Start Deck 100 set, a deck-box inclusion built to be played rather than chased, so demand rests on the Pokémon's loopy charm instead of rarity. The card shows Grumpig mid-dance in grey-blue against a bright, scribbled rainbow backdrop of coloured pillars. It arrived in December 2021, months after the same Grumpig appeared in English Battle Styles. The modelled guide sits at $3.50, down 5% on asks over 30 days with no copies traded; no PSA population is on file.
