Nature
Under a misshapen crescent moon, a dog boils as much nature as it can find.
Picture a weird-looking, misshapen crescent moon casting its light onto the scene of a dog boiling up everything you'd find in nature. Trees, sticks, mud, little animals. All of that is being boiled by this dog by the light of a weird-looking moon.

Destroying nature like this is the dog's way of practicing Zen (ぜん) Buddhism. As it breathes in the fumes from all of the different pieces of nature being boiled down, the dog gets really zen and chill.
Picture the dog kneeling in front of the pot of concentrated nature and breathing deeply as it practiced Zen. You kind of wish you could join it, considering how peaceful it looks.
