Ultimate Caterpillar

What's there to be afraid of about a caterpillar? Just go up and crush it to death in a minute. What if it's a mutated one? Mutated? Huh, still crush it to death in minutes! Really? What if it is a caterpillar that is hundreds of meters long, cannot be killed by missiles, and is omnipotent in the sky and on the earth? Dude, are you sure that's a caterpillar and not a dragon?
