The Queen's Domain Petrified Garden puzzle is a five-statue fountain. Five petrified monsters stand around the water, each set with a coloured gem, and the slots are on top of the fountain where they are easy to miss if you only look at ground level. Put each Trident key in the slot of the creature whose colour matches the key, press interact, and the garden wakes.

The Queen's Domain Petrified Garden puzzle: how to reach it
The garden is a hidden island. Fast travel to a warp station and jump off the platform during the teleport animation, and the game's own hint note calls it a leap of faith.
Reaching Lost King Ojjama, the whale boss inside the garden, takes four Wind Dashes, or three Wind Dashes plus the Cestus uppercut as an extra jump. Ojjama drops the Onyx key, which is the last of the five trident keys and the one that cannot be bought.
The hidden locations guide covers the other hidden areas too.
The colour to creature matching
| Creature on the statue | Gem colour | Key |
|---|---|---|
| Ratty Bug | Purple | Amethyst key |
| Slime | Blue | Sapphire key |
| Bat | Green | Emerald key |
| Deer or stag | Black | Onyx key |
| Homopiscium or fish-man | Red | Ruby key |
Matching statues elsewhere in the world act as hints. The Ratty Bug is out in the open on the Isle of Neasied, and the Bat is in the big red-water room of Deimpo Mausoleum.
Two things catch people out. The keys lose their colour once placed, so remember the order you used them in rather than reading them off the statue afterwards. And all five slots must be filled before the garden responds, so a single mismatched creature leaves the whole fountain dead. Where each of the five keys comes from is in the trident key guide.

What waking the garden does
With all five keys in, the garden comes alive and the Living Stone achievement pops. The petrified enemies wake up and attack, and new doors open to loot. Some statues attack the instant they wake, so arrive with full healing rather than trying to place the last key at low health.
Once the garden is awake, the glowing fish statues around it can be fought. Hit each one three or four times to wake it, and if nothing registers, switch weapons, because some weapons and effects do not damage them at all. These fights give extra loot and new bestiary entries.
The boss guide has the fight with Lost King Ojjama.
The second gate under the garden
A second gate in the same area needs all five trident keys and all four lenses of the Mask of Second Sight. That door under the Petrified Garden is the skull door where the 69 Strange Silver Etched Skulls are handed in, and it is part of the route to the fourth ending. The trident keys are therefore not optional loot.
The endings guide covers what the skull door opens.
