Little Sister, Big Trouble.
Episode Description:
Atom's younger sister, Uran, is born. Uran, who has the power to read the minds of animals, is told by a bird to notice the existence of an eerie pterosaur robot flying in the night sky, but when she tells Atom about it, he doesn't take her seriously, saying she must have been dreaming. Uran, who has no choice but to go looking for the pterosaur alone, learns that the pterosaur robot was created by Dr. Poppotore, an antiquity biologist, who was tricked by Katari, an opponent of robots. Uran tries to escape with the captured Poppotore, but is caught by Katari and trapped inside the pterosaur.
