"That was totally awesome! I've never danced with Fievel before." Olivia said, as she noticed the music box who fell out of the bag that she left it 2 years ago, "Hey! My music box! Where'd it came from?"
"I've got it." Twilight explained, "Two years ago, Queen Aleena thought me that you left it behind, that Captain Cat R. Waul, Hag Narissa, and The Junkyard Dogs have come for you. Luckily, I bought it for you." she continued, as Olivia's head showed images of the dancers' memories all around her.
"Well, in that case, we'll all be deal with it." Rainbow Dash added.
Olivia giggled as she clapped her hands for Pooka and Flower, who wanted to snuggle with Olivia. Then Gadget turned off the lights.
"Sleep well, my princess." Big Daddy Lou added. As he went to sleep, Flower was squished. Finally, he got out, Olivia chuckled, as she kicked Big Daddy Lou, who also chuckled.
"Sweet dreams, boys, Gadget, and Pooka." Olivia said, as she closed her eyes and went to sleep.
Meanwhile, inside the Junkyard Dogs' Hideout, the image of the sleeping Olivia was shown to Captain Cat R. Waul, Hag Narissa, Buster, Mooch, François, Sparky, and Ruby, who glared evilly at her.
"There she is, mon capitaine!" François gasped, as he pointed.
"Aww... Sound asleep in her little bed." Ruby said.
"And pleasant dreams to you... Princess Mousie...'" Cat R. Waul said, whispery evilly, as he started to swirl the crystal ball all around, "I'll get inside your mind... where you can't escape me...." He chuckled evilly.
Back in Hangman's tree, our heroes fell fast asleep as the green smoke crawled inside. The smoke swirled all over Olivia's forehead while Olivia yawned, and she smiled sleepily.
The dream began where Olivia (wearing a light blue Jasmine-esque outfit and a yellow hair-bow crown on her head) was laying down at a golden meadow, she saw her sisters May and Misty, who waved at her. Olivia also waved back. Misty smiled as she used her hands to make the butterflies fly towards Olivia.
Back into the real word, Olivia (still wearing her pajamas and hair-bow) began to sleepwalk after the butterflies. Then Pooka and Flower woke up. They noticed Olivia was missing. The puppy and skunk tried to open the door. They started to wake Fievel up.
Outside, it was stormy, windy, and rainy, and Olivia was still sleepwalking. Fade in her dreams, she follows May and Misty.
"Come on!" Misty called.
Olivia, May, and Misty played with the butterflies. Then they approached to Olivia's other sisters; Miss Kitty Mouse, Bridget, and Peepers, who were wearing swimsuits, while waving at them.
Miss Kitty was wearing her light blue one-piece swimsuit with snowflakes on it.
Bridget was wearing a teal blue one-piece swimsuit with flowers on it.
And Peepers was wearing her pink and light blue two-piece swimsuit with hearts on it.
"Oh, greetings!" Miss Kitty giggled.
"It's you!" Bridget smiled.
Then they jump into the water. The Pokémon Trainer sisters followed them. Back to the real world, Olivia was sleepwalking outside.
Back inside, Pooka and Flower attempted to wake Fievel up. Then he woke up.
"What, what, what, what, what, what, what, what? Pooka!" Fievel said, "Flower, what?"
Pooka barked, trying to get Fievel to understand.
"OLIVIA'S GONE!" Flower cried. Fievel turned around and saw Olivia's bed.
"Olivia... Olivia...!" Fievel snapped, shocked, as he runs over to rescue her. "Olivia!!"
Later back outside, the storm is still here. Fade to Olivia's dream, Olivia smiled sweetly. She saw Bernard who was wearing his red swimming trunks, with Miss Kitty, Bridget, and Peepers, joining him.
"Hello, sunshine!" Bernard smiled, as he chuckled.
"Hello!" Olivia smiled, while waving at Bernard, as she giggled.
"Jump in! Jump!" Bernard said.
"YAY!!" May and Misty shouted, as they jump into the water, making Bernard, Miss Kitty, Bridget, and Peepers splashed with laughter.
Olivia giggled. Back to the real world, Fievel was still looking for Olivia.
"OLIVIA!" Fievel called. He flies up to the mountain. Then he saw Olivia. "Olivia!" He cried, "Stop!!" He swooped down to Olivia, "OLIVIA! NO!!"
In the dream the voice is called under the water, "Yes. Jump!" It was Carface lurked in the shadows, glaring at Olivia, "The Dog and Cat Villain Curse!"
Olivia watched in horror, while she screamed in terror in her nightmare.
"JUMP!!!" Carface growled, "JUMP!!!!!!!"
The villains grabbed a frighten Olivia, while she screams. In the real world Fievel quickly saved Olivia from her death.
"Olivia! Olivia, wake up!! Wake up!" Fievel cried, as Olivia did, she gasped. She begins to panted, heavily.
"The Dog and Cat Villain Curse!" Olivia stammered.
"The whoa-- the what--?" Fievel exclaimed.
"Curse--!" Olivia cried.
"What are you talking about?" Fievel asked.
"I keep seeing faces. So many faces." Olivia sobbed. She hugged Fievel.
"It was a nightmare." Fievel said, as he hugs Olivia, "It's alright. You're safe, now." Olivia has stopped crying.
