Niko & Arkie's Space Adventure

Niko and Arkie are two brothers, 5- and 3-years old. Their parents took them to the Mauna Kea observatory to see the stars and planets. When their parents left the car to see what was causing a rumbling, a strange-looking alien came to the car. He asked Niko and Arkie to come with him to his planet and help save their children who had climbed into a wormhole and couldn't get out! That was the start of their big adventure!
