As lab animals they were used for experimentation purpose, many expiring due to reactions from various injections. The rabbit that was assigned to LT101 was taken by LabTech247 for his dipolar cellular distortions study. The rabbit ended up dying and LT247 responded to this by deposing of it in the furnace, but apparently not activating it, thus leaving the corpse to be picked up and given to LabTech062, who was ordered to inject the dead rabbit with experiment #410039. This inject caused the dead cells to resurrect within the Grunny.
