The people of a small USA town are aware of something unknown arriving to their town from outer space.
Falling Action
The towns people watch the news and anxiously waited for the invasion. They imagined what it would be like.
Resolution
A glow form the sky began pouring down on the town, it was yellow dust.
Research is conducted on the "invader." It keeps multiplying but is non-toxic.
People are disappointed that the invasion was peaceful. The invaders are more of a calm nuisance than a grand event. Their demise will be slow and calm.
