During art class, Sofia and the other students paint portraits of Minimus. After that, the class is given a new project - to make a model of their dream castle and bring it in for show-and-tell. Everyone is paired up for the project, and Sofia's partner is the shy Princess Vivian. Sofia goes over to introduce herself when the class is finished and says Vivian can come over to her castle to work on the project, but Vivian doesn't really want to. But she does agree to having Sofia go to her castle that afternoon instead. After school, Sofia is told rumors about Vivian by Amber and her friends: supposedly Vivian's parents are gnomes, she lives in a cave filled with glow-in-the-dark bats, and has a pet dragon. No one is sure if these rumors are true however, since Vivian never talks to anyone and no one has ever been to her castle.
Back home, Sofia is hanging out with James and Prince Zandar while they work on their castle, when Miranda arrives to inform her that the coachman is waiting to take her to Vivian's castle. After her excuse to not go doesn't work, Sofia tells her mother about hearing that Vivian is strange, and that when she tried talking to her Vivian didn't say much. Miranda says she will not really know what Vivian is like until she truly gets to know her. Clover also offers to accompany her, which makes Sofia feel better.
When they arrive at Vivian's castle - which is not a cave - Sofia is greeted by Vivian's mother, Queen Cecily, who suggests to Vivian that she show Sofia her room. Sofia is relieved that it seems none of the rumors about Vivian are true, but it turns out she does have a pet dragon, Crackle, who is very friendly. Sofia admits that she was a little scared to come over after hearing the rumors from the other girls, and Vivian reveals she is well aware of what they say about her, but is too shy to confront them about it. While the girls leave to go work on their dream castle, Clover is left with Crackle, who breathes fire when excited, and does so often since she has an excitable personality, to his dismay. Sofia has all kinds of ideas for the dream castle, but since Vivian can't think of anything, Sofia suggests they go to her favorite room in the castle to get an idea. Vivian brings her to the music room, and says the mandolin in particular is her favorite instrument. Sofia asks her to play it and offers to sing along. Eventually Vivian joins in the singing and, through the song, their castle is soon complete. Sofia tells her she should try talking to others at school so they can find out what kind of person she really is, but Vivian is still unsure.
The next day at school, Sofia and Vivian are talking about their dream castle when Amber and her friends enter the room, and Vivian ultimately gets too scared and runs away. Later that day, Sofia decides to go visit Vivian to check on her. Clover refuses to come along this time due to his fear of Crackle's fire breath, but in the end agrees to go with her. At Vivian's castle, Clover is quickly dragged off by Crackle to a room full of shish-kebabs, and finds out they taste better after she roasts them with her fire breath, making him re-think his opinion of her. Meanwhile, Sofia tells Vivian that everyone can get to know her tomorrow at show-and-tell, but Vivian would prefer that Sofia do all the talking, and nothing Sofia says makes her change her mind. When Sofia goes to retrieve Clover so they can leave, he shows her Crackle's talent for roasting food and his remark about talents gives her an idea. She goes back to Vivian's room and tells her she can play her mandolin while they both sing about the castle instead of talking about it, pointing out that Vivian became more confident after playing the mandolin last time.
The next day at show-and-tell, Amber and Hildegard present their two castles, one for gowns and the other for shoes. Next is James and Zandar's castle, which is basically a giant cannon. Finally it's Sofia and Vivian's turn. Vivian is scared at first, but with Sofia's encouragement, she is able to both play her instrument and sing without any problems. After they finish their presentation, Amber and the other girls come over, impressed by Vivian's musical talent and wanting to be friends.
