Anti-starvation "cheat"???

I am very interested, what is this???

This sim in the last stage of starvation. Of course, a ghost cannot die from starvation, however, this is still unexpected behaviour. I know that if a sim is starving but has something eatable in the inventory, it will eat it. However, this sim had nothing. On the last stage, she always starts to chaotically search her "pockets" and would always found this "something" you see on the picture. She eats it and fills her bar to about 70%. This action cannot be cancelled.

This is the mold-ghost by the way.
