It is unknown where the Slurp-A-Kins come from or when they first started working at the factory. Curdle noted that they were highly dedicated and were able to push the boundaries of runny cheese technology. Unfortunately, they eventually tired of creating runny cheese and started a "Hard Cheese Revolution". To begin with, the workers started by raising the pressure on the cheese vats, causing them to explode and erupt runny cheese all over the factory. This uprising coincided with Chuck D. Head's tour of the factory and forced him to join in the fightback against the rebels. Greater in number, the Slurp-A-Kins put up a good fight against Chuck, attempting to overwhelm him. In the end, they proved to be too weak, easily repelled by his brute strength and extending neck.
