In the vibrant world of Pokémon Pokopia, adventurers are invited to explore the enigmatic Bubbly Basin, a locale teeming with untold riches, including significant submerged artifacts. These ancient relics, once brought to Professor Trangrowth, can be transformed into distinctive furniture pieces, allowing players to imbue their virtual residences with unique flair. While these decorative items are also available for purchase or found across the landscape, unearthing a relic directly from a block is essential for it to be officially cataloged within your esteemed Ancient Artifact collection.

Locating these substantial lost sunken relics in Pokémon Pokopia involves a methodical approach within Bubbly Basin. Similar to the discovery of other relics, players must seek out blocks emitting a faint glow and then employ the Rock Smash ability to unearth their contents. A crucial distinction for these particular relics is that the glowing block must be situated underwater. Should a large relic be discovered in an area above the water's surface within Bubbly Basin, it will classify as a regular artifact. While searching underwater, you might also stumble upon other valuable items such as treasure maps, collectible dolls, music CDs, and mysterious slates. Upon retrieving a sunken relic, the next step is to visit the PC adjacent to the Pokémon Center in Bubbly Basin to contact Professor Tangrowth. The Professor will then appraise your finds, even if they are duplicates, helping you progress in your collection.

The extensive array of large sunken relics available in Pokémon Pokopia offers collectors a thrilling pursuit. If your primary goal isn't to complete the "Ancient Artifacts" log but rather to acquire specific items, the ingenious method of 3D printing provides an alternative. By simply capturing a photograph of an item owned by another player, you can replicate it for your own use. The pursuit of these relics enriches the game experience, encouraging exploration and engagement with the world's hidden depths.

Embarking on the quest for these submerged treasures in Pokémon Pokopia transcends mere gameplay; it embodies the spirit of discovery and perseverance. Each relic found, each puzzle solved, and each unique piece of furniture acquired contributes to a richer, more personalized adventure. This journey encourages players to delve deeper, not just into the game's aquatic environments, but into the broader narrative of exploration and collection, fostering a sense of accomplishment and creative expression within their virtual homes.
