When the king and his family left the  castle to see the ponies, the little girl and her horse foal were also there, and they noticed something was coming out of them "Ice?" The girl said curious "C'mon Spirit", and they started to follow them. When King Jack and his family arrived to the ponies' place, the little girl and her Mustang were spying them "Please, help me, it's... my son!" Jack screamed and the ponies started to come out from their hiding places "It's the king!" "And the queen" the ponies said surprised for their arrival "Ponies?" The girl said watching them, and a pink pony whispered "Shh, I can't listen", the foal licked the pony's cheek and said "How cute, I wanna adopt them". Meanwhile, a zebra with a brown cape named Zecora, come to cure Sonic; when she touched Vampirina's hand, she felt the power inside of her "Her powers, they came since she was born or by a spell?" Zecora asked "Since she was born, and it's growing stronger" the king answered "Get him close to me" Zecora said, and Rosalina get Sonic close to the zebra "For good it wasn't his heart; the heart is not easy to change, but it's easy convince the mind" Zecora said "Do what's better for him" King Jack said to Zecora "I'll recomend get rid of all the magic, including the magic's memories to be safe; but don't worry, the fun will stay" Zecora said touching Sonic's forehead with his new memories "He will feel okay" Zecora said "But he will forget that I have powers?" Vampirina asked worried "It's for his good" the king said to his daugther "Listen Vampirina, your power will be still growing; there's something very beautiful in it, but also is very dangerous. You have to learn to control it; your fear, will be your enemy" Zecora explained "No, we can protect her" Jack said and he told this to Zecora "She will control it, she'll learn. Untill then; we will close the gates, we will reduce the using, we will limit her contact with people and we will hide her power from everyone; including Sonic".
And that's what happened, the king and queen did all things they said to Zecora; and Vampirina, to keep herself away from Sonic so she doesn't hurt him, she wanted to stay in her room and don't play with Sonic anymore. But Sonic, everyday there was snowing, she wanted to play with his sister; and this is what happens:
Sonic: Vampirina? (Knocking the door)
🎵Do you wanna build a snowman?🎵
🎵Come on, let's go and play🎵
🎵I never see you anymore🎵
🎵Come out the door 🎵
🎵It's like you've gone away🎵
🎵We used to be best buddies🎵
🎵And now we're not🎵
🎵I wish you can tell me why🎵
🎵Do you wanna build a snowman?🎵
(Putting his lips on the keyhole)
🎵It doesn't have to be a snowman🎵
Vampirina: Go away Sonic!
Sonic: 🎵Okay, bye🎵
Meanwhile, Vee was looking at the window, but then, she froze it!
King Jack: The gloves will help you. See, hide it
Vampirina: Don't let...
Both: Noneone know
One year later, Sonic knocked Vee's door again.
Sonic: (knocking the door)
🎵Do you wanna build a snowman?🎵
🎵Or ride our bike around the halls?🎵
🎵I think some company is overdue🎵
🎵I've started talking with the pictures on the walls🎵
(To a picture) Don't give up John
🎵It gets a little lonely🎵
🎵All these empty rooms🎵
🎵Just watching the hours tick by🎵
(Doing a clock's sound)
Meanwhile, with Vampirina
Vampirina: I'm too scared, it's growing stronger!
King Jack: You know that it gets worse when you're altered, calm down
Vampirina: No! Don't touch me! Leave, I don't wanna hurt you!
The years passed and Vee didn't leave her room, and Sonic was still feeling lonely. One day, Jack and Rosalina needed to go in a trip to another place and their son and daugther give them a good farewell
Sonic: I'll see you in 2 weeks
Vampirina: You have to go?
King Jack: We're counting on you Vampirina
When their parents were on their trip, Sonic and Vee were waiting for them to come back. But they received bad news: their parents' boat sinked after they passed a big storm; and Jack and Rosalina... died. All kingdom of Arendelle were devastaded after losing their king and queen, especially their son and daugther; Vampirina was too sad that she didn't go to their funeral, but then... someone knocked the door, it was Sonic! (Who was looking for her after the funeral)
Sonic: (knocking the door) Vee?
🎵Please I know you're in there🎵
🎵People are asking where you've been🎵
🎵They say "have courage" and I'm trying to🎵
🎵I'm right out here for you🎵
🎵Just let me in🎵
🎵We only have each other🎵
🎵It's just you and me🎵
🎵What are we gonna do?🎵
(Crying)
🎵Do you wanna build a snowman?🎵
Now it was only Sonic and Vampirina on the kingdom. What are the kingdom going to do about it?
