Theme of the secret, actual final level from my upcoming-ish action platformer, Skye the Streamertail. Note the reprisals of the game's main themes.
After passing through the stunning tank, the birds' throats are slashed, usually by a mechanical blade, and blood begins rushing out of their bodies. Inevitably, the blade misses some birds who then proceed to the next station on the assembly line: the scalding tank. Here they are submerged in boiling hot water. Birds missed by the killing blade are boiled alive. This occurs so commonly, affecting millions of birds every year, that the industry has a term for these birds. They are called "redskins". According to Virgil Butler, a former Tyson slaughterhouse worker, "When this happens, the chickens flop, scream, kick, and their eyeballs pop out of their heads. Then, they often come out the other end with broken bones and disfigured and missing body parts because they've struggled so much in the tank."
Food for thought.
