Companion dice is a dice that will follow you around,sleep with you,and play with you! Unlike most dices this dice is not two but just one! Apeture Science has donated over 1,000 companion dice from a test chamber! The companion dice were happy that there were no incinerators at Fuzzland! Please do not be confused by the Aperture Science Companion Cube and our companion cube, they look the same and can be confusing. Our Companion Cube looks like a Aperture Science Comapnion Cube but they are different. Ours are alive and CAN feel pain. If you see a lifeless Companion Cube please report it to a expert.
