It can take a while to get used to the Jarhead. But the monsters keep it around because despite its fearsome appearance, it has a gentle heart. Even though they're pretty sure that it only has a brain.


The Jarhead looks like a large alien head or skull in an oblong jar filled with green fluid. Surrounding the base of the jar are purple tentacles and a small green plant. The jar bubbles as though the head is breathing and the eyes move and blink.

  • This decoration currently appears to only exist on the Vita version of the game.
    • Despite this, the sprite sheet, bin file, and xml file for it are present in mobile and PC version. So, the Jarhead is a fully functional decoration, but it isn't in the market.
