^{If on a mobile device, click here to see all of Wallter's dialogue.}

Appearance

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. Unlike most other NPCs, Wallter has more than 6 body parts, as he has 10 extra joints, implying he has the R15 rig.

He also wears a blue scarf which wraps around his neck with the end of the scarf extending out of the loop.

In his Halloween appearance, he wears a skeleton costume with a pumpkin mask that has his face painted in a glowing yellow color. In Halloween 2025 he wears a wide rocky-textured rectangular bag over his head with pink eyes, blue pupils and huge dark circles on the front, bearing a small resemblance to Eccles.

In his Christmas appearance, he wears a gingerbread man costume with his scarf now white, red and green buttons on him, and white stripes across his arms and legs.

In his Valentine’s appearance, he wears a pink scarf wrapped around his neck and pink heart sunglasses on his face.

In his 2024 April Ghouls' appearance, his face changed to resemble Eccles from NOKORI 残り with his body being disfigured and dances on idle. In his 2025 April Ghouls' appearance, he appears as Thomas Jefferson wearing a Miku binder.

In his Summer 2025 appearance, he wears white flower shaped sunglasses above his eyes and no longer wears a scarf.

Description

Wallter is a construction worker that mainly builds with concrete and bricks, and is particularly obsessed with drinking Wet Cement. 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, though he doesn't like being gifted Kitty, as seen by his interactions with Gnarpy.

Interactions

In Flatgrass, Wallter falls from the arch building and then proceeds to move towards the elevator, entering it if MR is not inside or if the elevator is not full. Wallter can exit the elevator on Hole in the Wall, Backrooms, gm_flatgrass, 3008 and Floppy Shoppy.

On the Hole in the Wall floor, Wallter will fit into the titular hole in the wall. From there, he will either seal the hole or slide through the hole and run away. On the Backrooms floor, Wallter exits the elevator and walks aimlessly. On the Intense Obby floor, Wallter will exit and do the obby as if they're a player, though players can beat him to the end.

Wallter will accept the Cheezburger, Fizz Up!, Cheese, Medkit, Wet Cement, Jerm Pop, Red Block!, Infinite Ice Cream, Dance Potion, Chocolate Milk, and Cake Slice. He will not accept the Magic Mirror, Fizz Jug, Kitty, Gas Mask, or Cooler.
