Revision 1

Overview

Roco Kingdom: World is filled with hidden content waiting to be discovered. Across the world map, players can find perfect spirit eggs tucked away in secret spots, hidden gacha machines that dispense exclusive outfits and resources, secret spirit encounters tied to specific NPCs and interactions, concealed dungeons brimming with rewards, and mystery eggs scattered across every region. This guide catalogs all known hidden content to help you track down everything the game has to offer.

6 Hidden Perfect Spirit Eggs

Six perfect spirit eggs are hidden throughout the world. Each one is obtained through a unique environmental puzzle or interaction sequence. Perfect eggs hatch into spirits with maximum base stats, making them some of the strongest starting points for spirit cultivation.

11 Hidden Gacha Machines

Eleven gacha machines are hidden across the world. Each one is slightly off the beaten path and dispenses a unique reward when interacted with. Finding and activating all 11 machines earns you an exclusive nameplate.

After activating all 11 hidden gacha machines, you receive the exclusive nameplate as a completion reward. Some machines are easy to spot if you explore thoroughly, while others require you to jump to platforms or talk to specific NPCs to reveal them.

Hidden Spirit Locations

Several spirits cannot be caught in the wild through normal encounters. Instead, they appear only after specific triggers, such as talking to certain NPCs, interacting with objects, or completing short quests.

Phantom House Hidden Dungeon

One of the most rewarding hidden dungeons is the Phantom House, located inside Annie's Shop in Coco Fruit Plaza. To unlock it, observe the shelf and select the third option (swap bottles 3 and 5, the same interaction that leads to the Perfect Little Night egg). Completing the Phantom House dungeon yields the following rewards:

• Little Night's Egg

• 80 Light Crystals

• 2 damaged King Balls

• Evil bloodline medicine

• 150 Unicorn Silver Coins

The dungeon features several puzzle rooms and spirit battles. Bring a well-rounded team because the enemies inside cover multiple element types.

25+ Hidden Dungeons

Beyond the Phantom House, over 25 hidden dungeons are scattered across the five major map regions. Combined, they yield approximately 6,000 Magic Dust and 22 perfect spirit eggs. Each dungeon has its own entry condition, ranging from simple exploration to solving environmental puzzles or defeating specific overworld enemies.

Check every cave entrance, suspicious rock formation, and interactable object as you explore. Many dungeons are hidden behind walls that can be broken by throwing spirits at them or by activating nearby switches.

34 Mystery Eggs

Thirty-four mystery eggs are scattered across the entire map. They are obtained by battling hidden NPCs or completing interaction puzzles in the overworld. Some of these eggs hatch into Shiny or Rainbow variants of existing spirits, making them highly sought after by collectors.

Mystery egg locations are not marked on the map. The best approach is to talk to every NPC you encounter and interact with any unusual objects. If an NPC challenges you to a battle out of nowhere, defeating them often rewards a mystery egg. Keep track of which eggs you have found using the in-game collection log to avoid revisiting cleared locations.

For the most efficient egg-hunting route, start with the regions closest to the fast-travel points and spiral outward. Cross-reference with the Gulu Balls you have available, since some interaction puzzles require throwing specific ball types at objects.
