Spring
As the alabaster tides recedes, warmth fills the air, liquid nourishment leaks through the roof. With newly required energy, they emerge from their shells, piercing through the ceiling into the light, farmers rejoice.
Summer
Temperatures rise to unbearable levels. Once mere children, now fully bloomed adults, they entice creatures big and small to spread their eggs and sperm.
Autumn
Flat irregular shapes, colors altered, from green to red, from green to yellow, from green to orange, deciduous in nature, they fall.
Winter
Frozen crystals of dihydrogen monoxide fall from the heavens, each one unique, forming a fluffy, alabaster sea.
