The boy looks at the crushed remains of the car and the small amounts of blood leaking out of the car. When he does not respond at first the lizard thinks he may have caused his boy some distress. Then a smile crosses the boy's face and he tells the iguana to do it again. It appears the boy likes having a giant rampaging reptile.
The iguana complies with the boys wishes and finds other cars and humans to crush. The boy giggled and told the iguana what a good lizard he was. After a few minutes the iguana spotted a small group of humans enter a home. He decided to see how the boy would like seeing an entire house being crushed.
Houses once seemed like such sturdy structures to him, but at his current size they looked like flimsy pieces of wood. He placed a foot on the home and slowly began to crush it. It was easy enough to do, all that was necessary was to put some of his weight on the foot. The house buckled and collapsed before his foot was halfway to the ground. The boy thought the whole thing was hilarious and laughed the whole time.
It was nice having fun with the boy. The iguana did not want him to get bored and tried to think of other things to do. Maybe he could start eating people or see what he could do at an even larger size.
