This, ladies and gentlemen, is a cry for help.
What you're seeing is the dark side of suicidefoodism—it has a bright side?—where the rush to die is shown in its proper context. To wit, the substance abuse and psychiatric issues that result from the animals' insistence on making objects of themselves.
This hallucinatory scene, this tableau with the vertiginous color sense of Van Gogh, is the headiest we've come across in years. While the sun stabs the sky and the water teems and seethes, the "food" animals float toward their doom.
As evidence of the deep wound in their psyches, take note of the two white flags of surrender and the chicken's "We give up!" posture. These animals aren't escaping: they are meeting their butchers head-on. Of course, one look at the cow's spiraling eyes is enough to make us wonder whether the poor animals even know where they are.
Regardless, they made a pact and they're in this thing together. When the end comes, which it will, soon, they'll face it like heroes. Disoriented, psychologically damaged heroes.
