Flight of the Unicorn is the second part of the eighteenth episode of American Dragon: Jake Long.
The episode starts off as Jake, Trixie, and Spud are taking a train to go have fun on their free day. They decide to go to the carnival, where Jake suddenly sees a sign that says that they have a unicorn. Trixie says that it is just a horse in a costume with a horn, and Spud sarcastically thanks her for ruining the fun. At the sideshow, they see a person that spits fire, and then they see a unicorn. Jake notices that the unicorn is real. When they leave, Jake calls Fu Dog, who tells Jake that he has to get the unicorn back with its herd. When they go inside again, Trixie and Spud distract one of the carnies, the unicorn makes a noise and the carnies notice that the kids are trying to take the unicorn. Jake, Trixie and Spud leave with the unicorn, while Jake turns into his dragon form and distracts them. When Jake goes back for Trixie and Spud, they are all in the middle of the road. Trixie finally gets the unicorn to move and they go very fast through horse racetracks. When Jake and Trixie and Spud lose the carnies, they go to the forest where they leave the unicorn to go with its herd. The unicorn leaves and Jake apologizes for ruining things. Trixie and Spud disagree and tell him that it was the best day ever as the episode ends.
