Mix and Mox are Maxwell's twin brothers, who are found in Grave Manor. They are found invisible. If the twins are given what they want, they teleport to another room.
They both wear beanies and shirts with ties. To keep people from mixing them up, Mix wears a green shirt and beanie and red pants, while Mox wears the exact opposite. A red shirt, a blue and red beanie, and green pants.
How to Unlock
They wanted something to play with, so give them a toy, such as a board game, a ball, two action figures, two handheld consoles, or a toy bomb.
The name of the shard they give may be a reference to the Grady Twins' quote from the horror movie The Shining.
