The Sellbots have expanded their operations into Toon HQ and established Field Offices that persist across every district simultaneously. Taking one down requires coordination across multiple groups of Toons — no single team can manage it alone. Inside the Field Offices, the Sellbots have stripped out enough silliness to disable certain gag types, so Toons must fight through the building's Annexes to recover stolen jokes before their full arsenal becomes available. At the top of the Annex, the Boiler oversees the high-pressure operations in the Sellbot sales room. The Boiler is a Boss Cog unlike anything encountered before — capable of putting even experienced Toons under enough pressure to make them fold. Bring it down to knock out power to the whole Annex and bring the Field Office closer to defeat.
