Pokémon Pokopia players can dig large lost sunken relics out of glowing underwater blocks in the Bubbly Basin area, then trade them with Professor Tangrowth for unique furniture to decorate their in-game homes. This guide explains how the process works and lists the specific relics discovered so far, helping players complete their "Ancient Artifacts" collection log.

To find a relic, players must locate a glowing block underwater and break it using Rock Smash, or use a Pokémon with the Search ability alongside the Dowsing Machine; relics found above water level are a separate, regular type. Once collected, players can visit the PC near the Bubbly Basin Pokémon Center to have Professor Tangrowth appraise the item, with duplicates possible. Relics found so far include a Windup Inkay, a Chimecho wind chime, running shoes, a Gyarados fountain, a Primarina statue, cycle shop and supermarket signs, a restaurant sign, and a Swampert squad rug; items can also be duplicated via 3D printing rather than digging.
