What's in the food at the Chum Bucket?

Plankton,a tiny green zooplankton, from the American television show, Spongbob Squarepants, runs the Chum Bucket, a restaurant across the street from the Krusty Krab (this information is from those of you who 1. don't watch Nickelodeon, 2. have never heard of Nickelodeon, and/or 3. don't know what Spongebob Squarepants is.) Even though he's a terrible cook(seriously, his computer wife Karen couldn't pay a guy to eat there), he continues to sell his chum recipes. Does anyone have any guesses as to what's in chum?
