The Ghastlierest Gibus (/'gæstliərɛst/ /ˈdʒaɪbəs/ gast-lee-er-est jahy-buhs) is an unlockable cosmetic item for all classes. It is an upgraded version of the Ghastlier Gibus. The item is very similar to the Ghastlier Gibus, but with the addition of a brown-irised eyeball inside the ripped top of the hat, sitting on a small red platform inside it. The eye is a symbol related to the Very Scary Halloween Special, meant to resemble the boss character in Eyeaduct, MONOCULUS.
Players that had earned the Ghastlier Gibus before the Very Scary Halloween Special update had their Ghastlier Gibus upgraded to a Ghastlierest Gibus.
