As the last alien vanishes, the little chicken leaps to his feat!
"Those creatures vanished! Nothing can do that! Yes, some animals can run fast, but those creatures didn't run away. They didn't fly away. They didn't dig a tunnel and crawl away. There is no water here so they couldn't swim away. They just vanished! If they can vanish, what else can they do?"
The little chicken has finally realized the truth. He is engaged in a struggle with forces beyond his experience, his comprehension and even his imagination.
Years later, scientific analysts, military strategists and other assorted 'armchair quarterbacks' will theorize that the little chicken should have reached this conclusion sooner.
