Fans of the Portal game series will absolutely flip once they lay eyes on the beverage chillers produced by the Companion Cube Ice Tray.
The Companion Cube is a recurring object in the Portal universe. It looks pretty much identical to the Weighted Storage Cubes seen throughout the game but instead of having the Aperture logo on the sides, Companion Cube sports a pink heart to help make you feel warm and fuzzy inside.
Even though the original companion Cube was thought to have been incinerated during an episode in the first Portal game, now, thanks to the Companion Cube Ice Tray, you can make all the companion cubes you want! You and your drinks will never have to feel lonely again.
