Roco Kingdom Jini is an unofficial fan resource for players seeking detailed reference data and practical tools for the Roco Kingdom game. Based on the Chinese-server official compendium and community contributions, the site organizes information about Jinies, including stats, traits, skills, evolutions, locations, and egg groups. Its database lists 375 Jinies, 82 alternate colors, and 96 seasonal entries, alongside 487 skills, 165 traits, and 30 natures.

The site also offers breeding and hatching support, with tools to find compatible mates or identify eggs by weight and size. Players can explore a Carosia world map featuring chests, collectibles, fruit, ore, sanctuaries, and waypoints. Additional resources include type matchups, a team builder, damage comparisons, an egg identifier, tier lists, items, and community teams organized by season. Collection and favorites tools help users track Jinies, while guides and redeem-code information provide further player resources. Roco Kingdom Jini notes that its translations are unofficial, uses pinyin for Jinies without verified official names, and that global-version content may differ.
