Wallter is a construction worker that mainly builds with concrete and bricks, and is particularly obsessed with drinking Gray Stuff (aka Wet Cement)—addicted to it, even. Wallter is well-meaning, polite, and extremely formal in his speech. His obsession with concrete forms a rift between him and Mannequin_Mark (also known as Mark), his ex husband who prefers wood as a building material and heavily dislikes concrete. Wallter refuses to believe that Gray Stuff is in any way harmful, and tends to insist that others try it out. His addiction to Gray Stuff was why he chose to divorce Mark. He has moved on entirely from his ex husband. Wallter has the appearance of a tall, grey humanoid figure with a beige torso, dark gray legs, and a spherical head with a drawn-on smile. He also wears a blue scarf which wraps around his neck with the end of the scarf extending out of the loop. Fun facts: Wallter seems to like cats. His birthday is February 17th. He plays the piano. He is gay. He is somewhere around 10 feet tall.
