Before Anna and Elsa were separated from each other, they are playing in the snow near Arendelle with their family.
"Hey, Elsa," Anna said to Elsa. "Do you want to build a snowman?" "Yes!" Elsa said gleefully. Then they ran to a wide open space for them play at.
The first thing they did when they got there was build a snowman. After the snowman is built, Elsa showed it to Anna and said in a funny voice, "Hi, I'm Olaf and I like warm hugs." "I love you, Olaf," said Anna as she hugged the snowman.
Then the two sisters engaged in more snow fun. They made snow angels, slid down snow hills (made by Elsa's magic), and went ice skating on a frozen pond.
Not too far away, a blue ice dragon is spying the girls without them noticing. As soon as it gets close enough to them, just when it was about to pounce on them, they run back to their parents after the sisters hear them calling for them. "We're coming!" shouted Anna. The dragon secretly follows them.
"Come on, Anna and Elsa, we're going home now," said the King.
"Mama, Papa, Elsa used her magic to make me some ice skates!" Anna said excitedly. "Well, that's very nice, dear," said the Queen.
Just as they were leaving, a shadow looms over them and Anna and Elsa scream in terror. The family looks up and sees that the shadow belonged to the same dragon that stalked Anna and Elsa. The dragon lets out an intimidating roar as it towers over them.
"Frostfire! Get out of here! Quick!" shouted the King. The Queen, Anna and Elsa fled to safety while the King and some guards stayed behind to fight the dragon.
Frostfire breathed ice onto a few guards, freezing them. "Come on, you horrible beast!" shouted the King. Frostfire lunged forward to attack.
In the present, a year after the great thaw in Arendelle, Anna suddenly bolted up in her bed, realizing that all this was just a nightmare.
Queen Elsa, having heard her sister's scream, entered the room. "Anna? Are you okay?"
"Oh, Elsa, it was horrible," said Anna.
"That same nightmare again?"
"We were children and we were playing in the snow. Frostfire came and attacked us."
"Relax, Anna," said Elsa, calming her sister down. "It was only a nightmare. Frostfire hasn't raided Arendelle since the year we were isolated from each other."
"Well, I hope we never hear of him again."
"So do I. Now come on. Breakfast is served."
