Lubna and Ali were going to the park. On their way they saw a little girl crying. They decided to help her. They asked, “Why are you crying?” The girl suddenly turned into an alien. The children were astounded. “Hello! My name is Zock and I need fuel for my spaceship,” the alien said. Lubna and Ali led it to the nearest petrol station and showed it the petrol. ”No this isn’t fuel that I use for my ship,” said Zock. “What kind of fuel do you need and how can we make it?” asked Lubna. “We will need the venom of an adder and ten thorns of cactus. Then we have to mix and heat them,” answered Zock. Luckily there was a botanical garden nearby. They made a plan to distract the guard. Zock imitated the sound of a fire alarm and the guard rushed to the other side. They hurriedly collected the thorns. Next, they went to the zoo. There again they faced the guard problem. Zock imitated strange sounds which disturbed the howler monkeys and they started howling and the guard ran towards them. Zock took out a strange looking flask in which he took the venom. They went home, mixed and heated it. Before Zock went home, he gave them a special whistle and said, “If you ever need me, blow this whistle and I’ll be there.” With that he jumped into his spaceship and headed home.
