Plankton’s Old Chum

Plankton cooks a batch of chum that goes bad, and he has to find a place to hide it. He runs into SpongeBob and gets him to hide the chum, convincing him that he is actually hiding presents for a Christmas-like holiday known as “Chum Day”. When the rotten chum fails to hold and explodes all over the city, coming down like snow, SpongeBob shows Bikini Bottom of the true meaning of Chum Day.
