Precure All Stars: Harmonic Rainbow!

The Rainbow Chest

6 girls sat giggling. The harmony precure. It was Sunday evening and they were laughing in the castle of equestria valley. Having a slumber party.
Twilight cuddled spike her baby sized dragon.
"Okay geography will be a breeze!" Rainbow dash cheered.
"Break from the precure stuff, just some R&R" Rarity smiled as she painted her nails.
"Um Rarity, can you stop that." Applejack said annoyed.
"Got to have my hands look good." She smirked playfully.
Pinkie pie bounced. "And a princess!"
They all looked at twilight. She had been promoted to princess hood after their last precure mission. After all they been through they were sure to stay friends forever. Twilight looked at a picture in her book. It was a photograph of a crystal shaped box.
Spike looked. "That's the legendary precure rainbow chest. It was rumored to appear to power up precure!" The girls looked at the picture one by one in awe. A short burp later, spike erupted a firery scroll.
Fluttershy caught it and unrolled it.
"The cherry blossom festival!" She gasped. "It's gonna be this year for all the precure!"
Pinkie squealed. "There are more precures??"
"I wonder if they dress as fabulous as we do?" Rarity remarked.
Twilight wondered in awe. More precures besides them! She wondered what they thought about being a leader.
"I bet they play sports!" Rainbow exclaimed.
"And adorable fairy pets!" Fluttershy nodded.
"Don't we have to plan all this y'all.." Applejack muttered.
The girls froze sheepishly.
"Right" they said.
