The Eyestalk Containment Box was first seen in Mars' parents' bedroom, hanging over their bed. It's purpose was to stop eyestalks from whispering to Mars. It did not succeed in this mission.[1]
Appearance
It vaguely look like a bizarre decoration. It's walls are made of semi-transparent green material, and the frame appears to be metal. It's aesthetic suggests it may have been constructed using Guardian technology.
Contents
Prior to being opened it contained 3 eyestalks.
