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.

Perfect Memory Stone | Peter Avenue | Collect all 5 Poke Balls scattered on the elevated platforms |

Perfect Crystal Snail | Alchemy Field cliff | Summon three spirits to destroy the large crystal formation on the cliff edge |
Perfect Jelly | Underground Tunnel | Navigate through the tunnel and reach the very end to claim the egg |
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. These hidden spirits are split between the town and shop areas and the wider wilderness zones.
Town and Shop District
The following hidden spirits are found within the town and shop areas of Roco Kingdom. Most involve talking to specific NPCs or interacting with shop objects.

Spirit | Location | How to Find |
|---|---|---|
Mechanical Fang (机械牙) | West Shop Street | Talk to the cubic NPC near the street corner. He assigns a 3-day material collection task. Complete all three days of deliveries to receive this spirit as a reward. |
Little Night (小夜) | Annie's Shop | Tap the third bottle on the shelf inside Annie's Shop. A wandering girl appears nearby. Interact with her while she is idle to trigger the spirit encounter. |
Demon Wolf (恶魔狼) | West Shop Street | Chat with the NPC named Chloe on West Shop Street and complete the short task she assigns. The spirit is given as a direct reward upon task completion. |
Crispy Sweet (酥酥甜) | Peter Avenue Dessert Shop | Speak with the shop manager behind the counter in the dessert shop on Peter Avenue. The spirit is obtained through dialogue. |
Wilderness
These hidden spirits are scattered across the open-world wilderness zones. They typically require environmental interaction, such as throwing spirits at objects or finding hidden interactables.
Spirit | Location | How to Find |
|---|---|---|
Dudu Pot (嘟嘟煲) | Near alchemy furnaces (multiple locations) | Spawns near alchemy furnaces scattered across the map on a probability basis. Monitor multiple furnace locations and use server switching for better efficiency. The spawn is random, so patience is required. |
Memory Stone (记忆石) | Above Dreambeast Forest (梦兽之森) | Locate the book lying on the ground above Dreambeast Forest. Strike the book to activate the encounter. The spirit appears immediately after the interaction. |
Small Box Monster (小箱怪) | Below Holy Outpost (圣地前哨站) | Find a box sitting on the ground below Holy Outpost. Interact with it to discover it is actually a disguised spirit and trigger the battle. |
Flower Butterfly (花衣蝶) | Left side of Abundant Valley (丰裕之谷) | Locate the stone statue on the left side of Abundant Valley. Throw a water-type spirit at the statue to trigger the Flower Butterfly encounter. |
Shadow Tree (幽影树) | Moon Rabbit Dark Harbor (月兔暗港), shipwreck area | Head to the shipwreck area of Moon Rabbit Dark Harbor. Find the tree stump near the wrecked ship and throw a spirit at it to summon the Shadow Tree. |
Tips for Hidden Spirit Hunting
Reserve backpack space before hunting task-based spirits. Some hidden spirits require you to collect or carry specific materials as part of the trigger quest, and a full inventory will block progress.
Use server switching for probability-based spawns like Dudu Pot. If the spirit does not appear at one furnace location, switch servers and check again. This resets the random spawn timer.
Check both the map and the minimap for unusual icons or NPC markers that might indicate a hidden interaction point.
Bring a variety of spirit types when exploring the wilderness. Some triggers require throwing a specific element type at an object (such as water-type for the Flower Butterfly stone statue).
Phantom House Hidden Dungeon
One of the most rewarding hidden dungeons is the Phantom House (幻影屋), 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.
Nightmare Eve (朔夜伊芙)
Deep within the Phantom House dungeon, players can encounter and obtain Nightmare Eve (朔夜伊芙 / Shuoye Yifu), a powerful spirit available at level 48. Nightmare Eve is exclusive to the Phantom House and cannot be found anywhere else in the game. Reaching level 48 is a prerequisite for this encounter, so lower-level players should focus on clearing the earlier Phantom House rooms first and return when they meet the level requirement.
Nightmare Eve is considered one of the strongest hidden spirits in the game, making the Phantom House well worth revisiting once you have a sufficiently leveled team.
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.
