Grandpa, Fu Dog, and Jake go on a mission to catch a goblin named Ralph. It seems that the Huntsman is going to retrieve the Orb of Malorphus. After he gets caught, Fu performs a truth spell on him and retrieves very useful information. He has a job to collect the Orb of Malorphus from the Huntsman and ship it to Ohio.
Fu Dog makes a potion for Jake to tap into the ability to shape shift into anyone he wants to be. When Jake takes that potion he transforms into Fu Dog and Grandpa and makes jokes about them.
In the park, the Huntsman is waiting for Ralph. Jake transforms into him and goes to retrieve the Orb of Malorphus. Then Jake acts like Ralph to convince the Huntsman that he is Ralph. As the Huntsman points at him, Jake thinks that he is going to shoot him, but a message appears and the Huntsman says that he will have to bring it the next day, and they disappear.
When it is time for the parent-teacher conference, Jake transforms into one of the teachers and tells his parents that their meeting is in another room. Then Jake transforms into his mother and tells Professor Rotwood that he is just jealous, and Jake leaves. Then he transforms into Professor Rotwood and goes to talk to his parents. Jake acts silly to make Professor Rotwood look silly and dumb, much to the anger of his parents.
In the hall way Jake spots Rose, and transforms into her favorite pop star Jared MacArthur, but they make him play his guitar and sing and he fails to do so, then leaves. Outside in the skate park he shape shifts into a professional and makes the bully let Trixie and Spud skate.
That night when it is time for him to retrieve the Orb, his leg doesn't change into Ralph's - he just shakes it and turns into Ralph's leg. When Jake leaves, Grandpa believes that Jake has misused his shape shifting powers. As he is talking to the Huntsman, the Huntsman is about to give the Orb to Jake, but as Jake walks away he starts transforming into Grandpa, his mom, Professor Rotwood, Fu Dog - everyone that he has shape shifted into. He eventually stops when he transforms into Jared MacArthur.
He then fights with the Huntsgirl and captures her. Later, Grandpa and Fu Dog take Ralph to lead them into Jake and the Huntsman, and just as Jake's head is about to transform back, Fu Dog turns off the lights, and Jake manages to turn into his dragon form and escape. The Huntsgirl and Jake fight, but as the Huntsman and the Huntsgirl decide to retreat, the Orb is about to fall down but Jake catches it.
Outside of his school, Jake and Grandpa talk about what happened. Grandpa asks Jake if he has misused his shape shifting powers, and Jake tells him that he didn't but at that moment they see Jake's mom and Professor Rotwood arguing, and Rose on the news talking about the singer. Then Trixie and Spud come and tell them about the skater. Jake smiles at Grandpa and Grandpa yells, "Jake!" as the episode ends.
