Once upon a time there was a lizard walking slowly from twig to twig in a bush in search for his next meal. He noticed right ahead a tasty spider sleeping in his web. The lizard approached its prey carefully and swiftly lashed out with his tongue in the hope that he would catch the spider and eat it.
But the spider was rather large and so was his intricate web built there in the bushes to catch unsuspecting insects. Sure enough, the lizard got his tongue entangled in the web. As he retreated he pulled the web with him and so awakened the spider.
The spider, thinking he had got someone trapped in his web moved forward and tried to entangle the lizard even more in the sticky web. That way, his prey would eventually die and be ready as a next meal.
