Masky is a female contestant in Object Overload and its reboot.
Masky appears to be a drama theatre mask that originated in ancient Greece, but it is unknown if she is the comedy (Thalia) or tragedy (Melpomene) mask. Half of her body is teal, and the other is peach.
Masky is usually concerned about situations and is rather timid. In the reboot's intro, she is semingly doing a play, presumably a drama play, to her audience, which were Snow Globe and Popcorn.
Masky is one of the three contestants that were originally going to be cut from the reboot but were able to stay. The other two being Picture and Soccer Ball.
