The Chompbot factory has a conveyer belt supplying Chomp Bot bodies, a hammer-like machine attaching the heads, and a warehouse where the finished Chomp Bots are stored.
At fixed times in the level (namely, wave 6 and 10 of Campaign and the only wave of Iron Challenge), the red Siren of the factory will flash, while the doors on the warehouse are opened to release 2-3 Chomp Bots. The Chomp Bots then proceed rightward to the exit just like regular enemies. They give gold when killed.
- Occasionally, the produced Chomp Bot has a head that belongs to various other robots, including BB-8, Gir, WALL-E and Marvin the Paranoid Android. This does not affect the spawned enemies.
