The Chaos Beam is something that Baconman feels he cannot allow Eggman to learn about. It is mentioned in the intro to chapter 2 of Eggman's Adventure, and then never brought up again. It might be assumed that the Chaos Beam is the name of the beam that destroyed Eggman's base at the beginning of the game. However, if this is the case, it is unclear why Baconman assumes Eggman is unaware of the beam, since he was present at the time of the base's destruction.
