It probably started with seeds that were dumped carelessly on the side of the road. After a while, the seeds sprouted. The pumpkin then spreads with its broad green leaves until then it has exposed its flowers to the morning sun, and also to the beetles and insects attracted to it. The flower period then ends, and the pumpkin is ready to bear its fruits. Nearby, some kind of edible mushroom also seemed eager to expose itself to the morning sun. They glow.
Elsewhere, butterflies spread their wings to absorb the warm morning sun, and glow themselves with it. At that time, dragonflies flew and landed in good places for them to ambush prey. Their wings glowed in the morning sun.
But that's not all, in places covered by bushes or leaves, rays of morning sunlight penetrate into there, providing an opportunity for the leaves and flowers down there to glow. It was a happy morning. Morning glow.
