 Trixie accidentally breaks her mother s expensive crystal vase. Jake and Spud work with her to raise money to replace it, but they re having no luck using traditional means. Their Mythology teacher, Prof. Rotwood, has offered $500 for physical proof of magical creatures. Jake tries selling photos of himself, scales, and claw trimmings, but Rotwood (not really knowing what dragons are like) dismisses his evidence. Later, during a battle with Thorn the Huntsgirl, Jake is knocked unconscious and lands right in front of Trixie and Spud. They take him to Rotwood s and sell him, not knowing that The Am-Drag is really their best friend. After getting the cash, they go to Jake s house to tell him the good news. But waiting in his room, they see the computer pictures Jake took of himself transforming into the Am-Drag. They then realize that they must buy the dragon back from their teacher.
