How to open Sun Doors in Slime Rancher 2: Into the Labyrinth

After entering Slime Rancher 2’s Grey Labyrinth, meeting some shadow slimes, and uncovering a few secrets, you’ll notice contraptions that look like sundials. You’ll even find various doors with sundial puzzles attached but no clear indicators for opening them aside from a hint from Gigi.

Fortunately, while it may seem tricky at first, the solution is easier than you’d think. Here’s how to open these sun doors and dials in Slime Rancher 2’s Into the Labyrinth update.

How to turn Sun Door dials in Slime Rancher 2: Into the Labyrinth

Turning the sundial and unlocking any doors or secrets behind them requires shooting Shadow Slime Plorts into their green circle. In the center of this contraption is a green circle that, by throwing a Shadow Plort in, slowly rotates the sundial until a moon appears instead.

The idea behind this puzzle is that, by using shadows and darkness, you’ll cause the Sun to set and the moon to rise. Well, at least that’s my interpretation of it. Regardless of its lore, you’ll need Shadow Plorts for this. You won’t just need a few, either. You need a ton of them. I’m talking well over 100 to open every Sun door and lock.

One regular Sun contraption costs around 25 Shadow Plorts to unlock, while a door requires around 50 to 60. This changes depending on the location within Grey Labyrinth. Even then, it’s still a lot to carry at one time, especially with how Shadow Slimes behave.

The rewards you get from unlocking a Sun Door or other dial puzzles depend on its location. While a normal contraption typically gives you a decoration or gadget recipe, doors often unlock new areas of the map, important puzzle nodes, or items like yellow portals that transform unstable materials.
