A chill-machine is a device that can turn an entire Zone into a frozen wasteland. Invented by The Chiller, it was unleashed on the Pleasant Zone after its inhabitants mocked the scientist. The Freedom Fighters infiltrated The Chiller's base and gave Sonic the Hedgehog the chance to operate the machine himself, reversing its effects and saving the Zone.
The machine has six settings, from coldest to warmest:
- Freezing
- Isn't It Cold
- Chilly
- Brisk
- Warm
- T-Shirt
Furthermore, each panel was colour-coded, with a gradual change in shade denoting how hot or cold the environment was. When a hot setting is selected, the screen would show hues of red and orange, whilst a cold setting was pictured by shades of blue. A screen at the top shows exactly what setting the machine is on, mirroring the colour shown in its respective panel.
The machine was never actually destroyed by Sonic, leaving it open to another use by The Chiller.
