Describe the unusual situation that occured at the zoo on dudleys birthday

At the zoo, the Dursleys spoil Dudley and his friend Piers, neglecting Harry as usual. In the reptile house, Harry pays close attention to a boa constrictor and is astonished when he is able to have a conversation with it. Noticing what Harry is doing, Piers calls over Mr. Dursley and Dudley, who pushes Harry aside to get a better look at the snake. At this moment, the glass front of the snake’s tank vanishes and the boa constrictor slithers out onto the floor. Dudley and Piers claim that the snake attacked them. The Dursleys are in shock. At home, Harry is punished for the snake incident, being sent to his cupboard without any food, though he feels he had nothing to do with what happened.
