Passage: Two aliens, Nukie and Miko, spend their time flying through space in the form of stars and looking for fun. The two come across the planet Earth and, while trying to survey the planet, get caught in its gravitational pull and end up crash landing. During the crash, the two are separated, with Nukie ending up in the African savanna and Miko falling into the hands of a Space Federation in the United States. Upon discovering Miko's crash site, the agency take the alien in to perform tests on him, while Miko cries out for Nukie. Miko reaches out to Nukie telepathically and informs him that he is being held captive in America. The head of the operation, Dr. Glynn sends Dr. Eric Harvey to Nairobi to investigate the other crash site. During their experiments, the scientists discover that Miko is a being made of pure energy.
Nukie, meanwhile, begins to explore his surroundings, attempting to communicate telepathically with the animals he encounters to ascertain the location of America. The animals don't understand and – much to Nukie's frustration – run away. He then comes across two children, Tiko and Toki, who seem to be able to understand Nukie. He asks them for their help with finding America, but they run off vowing not to tell anybody about what has happened.
In America, Miko is subjected to more painful testing to explore his physical makeup. Miko's brain patterns show images of the animals which Nukie sees, indicating that Nukie is transmitting his brainwaves to Miko. Nukie decides to rest in the shade of a tree, turning invisible as he does so. Tiko and Toki pass by and Nukie is awoken by a flock of birds, becoming visible once more. He surmises that his light beam transformer must be working once more, and he succeeds in flying. Landing near a stream, he tastes the water and notices his reflection, which he claims is different from usual.
What's the name of the person subjecting Niko's counterpart to painful testing?
