Mannequin_Mark, better known as just Mark, is usually a friendly, well-meaning construction worker, but on occasion can be a bit of a nervous wreck. They mostly talk about wood and woodworking, with them having a general dislike for all other building materials. They can also be extremely stubborn when it comes to construction material, praising wood above everything else. They specifically dislike concrete to the point of violence against players who drink Wet Cement in front of him. Due to his tastes in building materials, he and Wallter don't get along, and are often hostile in their interactions. Despite this, it is hinted that Mark still loves Wallter despite his preference for concrete. He has severe religious trauma from his family in the cult, and has run away from it long ago.

Wallter is a construction worker that mainly builds with concrete and bricks, and is particularly obsessed with drinking Wet Cement, completely addicted. Wallter is well-meaning, polite, and extremely formal in his speech. His obsession with concrete forms a rift between him and Mannequin_Mark, who prefers wood as a building material and heavily dislikes concrete. As seen in his dialogue, he refuses to believe that Wet Cement is in any way harmful, and tends to insist that others try it out. Wallter seems to like cats. He does not miss Mark, and in fact dislikes his ex husband. He does not show up in the opening scene.

Glevil is Mark's cousin, and the leader of the cult that worships The Great One; the tree that the Mannequins were carved from. He makes sure his teachings get through, carving strips of wood off any disobeying mannequins, and being physically violent toward intruders purposefully trying to shut him down. Despite this, his demeanor tends to be friendly and considerate, yet underneath is a manipulative cult leader worshipping a corrupted god of dreams. He is welcome to any visitors, as long as they pay a price and stay the whole sermon.
