Players unlock Sun Doors in Slime Rancher 2 by using Shadow Plorts

In Slime Rancher 2's Grey Labyrinth, players encounter sundial-like contraptions and doors with puzzles. To open these, players must shoot Shadow Slime Plorts into a green circle at the center of the sundial. Unlocking a regular sundial requires about 25 Shadow Plorts, while doors need 50 to 60, depending on their location. Players will need over 100 plorts to access all Sun doors and puzzles. Rewards for unlocking these doors vary. Normal contraptions provide decorations or gadget recipes, while doors often lead to new map areas, important puzzle nodes, or items like yellow portals.
