The Jack 'O Lantern Mask is a vanity item uncommonly dropped by Headless Horsemen. The inventory icon shows it as unlit, but upon placing it in the armor slot, it is rendered with a glowing pattern over the face. This is visible even if in darkness or stealth from Shroomite/Vortex armor/Psycho Knife. When displayed on a Mannequin, it is shown without the glow. Additionally, using dyes on the mask will change the color of the pumpkin, while leaving the glow unaffected, which may be unintentional.
- The glowing pattern is rendered separately from the sprite, and does not appear pixellated at any zoom level.
