Six friends visited the zoo on a summer day and saw many animals including turtles, snakes, monkeys, bears, elephants, and birds. While watching the animals, some of the children got scared by snakes or when a bear growled. Later, the lions escaped from their cage and chased the children and visitors. The children fled into a dark cave to escape, but were startled by bats. Zookeepers quickly caught the lions and rescued the children. The children then suggested to the zookeepers that the animals be kept in more natural habitats.
