The Chomp Bar is a milk chocolate bar with crisped rice mixed inside it.
While the Chicago Ghostbusters spoke at Nevermore Elementary School, a student offered Ron Alexander a Chomp bar. Ron quickly snatched it out of the boy's hand and ate it as he continued talking. A few months later, in December, Peter Venkman gave a Chomp Bar to a would-be victim of the Sinterklaas Ghost to take her mind off the traumatic ordeal. A Chomp bar was present on one of the tables in his apartment when he spoke with the other Ghostbusters over the phone about the Poveglia case.
