It is a strange alien squid-like creature that is used by the aliens as a food source. Alien squid food replenishes a very minor amount of health, so it is seemingly a "poor" consumable to regain lost health, when compared to other health restoration consumable items. However, since the food is weightless, a huge amount can be carried without fear of being weighed down.
Alien squid food can commonly be found on tables throughout all sectors of Mothership Zeta.
It can also be found on aliens and alien workers.
The food sanitizer does not increase the amount of health given by this item.
