"Dragon's Breath" is the second episode of American Dragon: Jake Long.
Jake sees a bunch of trolls and goblins screaming out of the sewers. Jake turns into his dragon form and sees a strange humanoid creature that steals souls. After Jake scared the creature, his breath became smelly.
Jake and Fu visit a magical place called Magus Bizarre. Jake meets an arachnid named Veronica, but he couldn't choose her because of her eight hairy spider legs (Fu thought Jake might be a leg man). Fu introduces two magical girls called Oracles to Jake: Sara (who sees bad things) and Kara (who sees good things). Jake sees a teenage girl named Jasmine, but Fu gets grabbed by an ogre and meets his old foe, Herbert the Goblin. Jake sees Fu getting tortured by Herbert and the ogre. Jake fights the two foes and he beats up the ogre and grabs Herbert and throws him next to the ogre.
Jasmine waves bye to Jake and she has glowing red eyes. Jake goes with Jasmine to the school dance, but Susan sends a message to her dad (Lao Shi) that Jasmine has red eyes. Lao Shi realized that Jasmine was a Nix, which was a creature that was harmless and beautiful during the day, but turns into a monster that steals souls when the moon reaches the center of the night sky.
Jasmine turns into her monster form and steals souls from every student at the dance. Lao Shi and Fu arrived and Lao Shi fights Jasmine. Fu tosses the potion to Jake, but Jake accidentally drinks the potion. He finds out that he wasn't supposed to drink it, but instead pour it on the Nix. The potion redages a potion who ever touches it becomes powerless, like sphinx hair.
Lao Shi also got his soul stolen by Jasmine. Jake knocks her out and she returns all the souls back to the students. The next day, Jake returns Jasmine back to Magus Bizarre and she continuously apologizes for the night, but Jake tells her that he is to blame since he didn't heed her warnings. After both forgive the other, Jake says he hopes the souls went to their original bodies. At the school, Spud's voice sounded like Trixie's and Trixie's voice sounded like Spud's.
