One sunny afternoon, Susie was playing in her garden. Next to her, her dog Fafik was jumping and her little brother Franek was building a huge mountain out of the sand. As Zuzia bent down to pick up a colourful pebble, she suddenly heard a soft buzzing sound. She looked into the grass and saw something she had never seen before! Amidst the blades sat a tiny silver robot. Its eyes glowed blue and it had a flickering antenna on its back. Fafik was very curious, so he began to gently sniff the newcomer. "Who are you?" asked Susie in surprise. The robot raised its head and said in a low voice: "I am Miku, the robot from the moon. I got lost during my space journey! I need help to get back to my ship." Susie and Franek looked at each other in disbelief, then smiled broadly. "We'll help you, Miku!" said Susie. The robot handed them a shiny map on which coloured dots glowed, leading to a hidden place. The children set off following the map's directions. On the way, they passed strange rustling bushes, jumped over puddles and found a glowing stone hidden under an old tree. Suddenly the sun came out from behind the clouds and lit up the garden even brighter. When they looked at the map, they saw that one of the dots had started to flicker red. Susie stopped and said in a whisper: "Franek, Fafik, Miku.... I think we're very close. But what's that strange light under that bush? Is that where the entrance to the spaceship is, or something even more amazing?"
