Chopped Liver is a jar of chopped liver that only appears in the episode, "Growth Spout."
It is in a jar with a light blue lid and the actual contents in it is light purple.
In the episode, the chopped liver is able to talk, just like the biscuit that was lying beside him in Mr. Krabs' cupboard.
Both have apparently gone unnoticed by Mr. Krabs for sometime. The chopped liver is mostly used as a gag only, for when the biscuit says "What am I, chopped liver?" The chopped liver says, "No, that's what I am."
