Niko and Saga go to Oona, the Leader and Grandpa and tell them they saw wolves. Just then, Niko spots two wolves named Smiley and Specs, so he and Saga run back to the herd while Julius distracts the wolves. With encouragement from Julius, Niko tries to fly by jumping off a tree, but ends upside down. The next day, Niko goes to Antler Hill with Saga and tries and fails to fly again, just before Julius arrives and tries to get Niko to return to Home Valley, but to no avail.
That night, Niko asks his mother Oona to tell him about how she met his father to which she does and says that he was one of the Flying Forces. Niko tells Julius that he is going to Antler Hill to practice flying, but is overheard by his friend Saga and her father the herd's leader, who forbids Niko to leave Home Valley as wolves are out there, but Niko and Saga secretly plan to go Antler Hill the next day. He then tries to fly but falls onto the ground and is teased by two other reindeer youngsters, but Julius tells Niko to ignore them and walk away, before throwing snowballs at them when they continue to taunt Niko. Niko first appears when he watches the Flying Forces test flying and ends up knocking down Grandpa while running.
