As Sonata swam through the air behind her pony guide, she started singing idly to herself. "If everyone is not special, maybe you can be what you want to be! Broccoli! Colostomy! A zoo camel! FLAMBE!!"
Pinkie, Fluttershy, and Rainbow all stopped and stared at her.
"...what?"" Rainbow choked out along with a bark of laughter.
Sonata shrugged. "It's the theme song to this show I like," she said.
"Oh my," Fluttershy said, blinking. "Well. That's...interesting?"
"Waaaaaait a second," Pinkie said suspiciously, jumping up in the air and hanging in front of Sonata, eyes narrowed. "I thought you couldn't sing anymore?"
Sonata blinked in realization. "Oh! Well, I mean...not usually. I mean, we can sing, just not...y'know...carry a tune." She looked down at her own chest. "Maybe it's because my magic is regenerating?"
Pinkie shrugged and settled back to the ground. "Fair enough."
As the little group continued on its merry way, Sonata started singing again. "TV says donuts are high fat kazoo, found a hobo in my room! It's Princess Leia, the yodel of life! Gimme back my sweater or I'll play the guitar!"
Rainbow braked in midair with an audible screech. "Okay, there is no way that's even a real song."
Pinkie stared up at Sonata. "That was too random even for me!"
Fluttershy tilted her head curiously. "Was that...was that supposed to be a threat? The guitar thing? Because that's a weird thing to threaten somepony with."
Sonata giggled sheepishly. "It's just something silly I heard on the Internet," she said.
The ponies looked at each other. "What's an Internet?" Rainbow asked.
"It's this thingie humans have where they can look at pictures of cats and stuff," Sonata said. "And lots of boring words, and..." Her eyes glazed over. "And some stuff Adagio likes to look at that makes my soul feel dirty..."
"Ooh!" Pinkie said brightly, reaching into her mane. "I have some purifying salt here somewhere!"
"Oh goodie!" Sonata said, clapping her hooves. Pinkie pulled out a big glass shaker and tossed it up into the air. Sonata caught it and upended it over herself.
As the twinkling granular dust showered over her, glittering in the sunlight, she blinked. "Umm, Pinkie Pie? This is purifying sugar," she said.
Pinkie blinked. "Oh! Sorry."
Sonata beamed. "No worries! Sugar's WAY better than salt!" She did a loop in the air, giggling happily.
Pinkie giggled too, bouncing up and down in place. "I know, right? I mean, we all need salt and it helps baking and stuff but who can say no to a whole bunch of yummy delicious sugar?"
Rainbow's irises shrank to pinpricks in sheer dread. "Oh Celestia," she mumbled. "There's two of them now."
Fluttershy huddled into herself. "So many bad memories," she moaned.
"Oh hey! We'd better get to the schoolhouse if we wanna keep this tour going!" Pinkie said suddenly, pronking off in the direction they'd been heading.
"Sure seems to be takin' longer than usual to get there," Rainbow said as she, Sonata, and a reluctant Fluttershy followed.
"I don't care if we never get there!" Sonata said happily. "I'm having more fun than I've had in forever!" She undulated around Pinkie, rose up into the air, and started singing again. "Breakdown! Wahoo reaction, now a Gucci cola sale! She sucks he sucks, Gengar power! Now I've got to lather barroom cheese! Obi-Wan coaches! IIIIII AM IIIIIMPAAAAAAACTOOOOOO!"
As her guides stared oddly at her, something in the distance exploded. A scream dopplered toward them; after a moment they heard a filly's voice screaming "DA-DA-DAAAAAAAASH!"
And then a small orange comet slammed into Rainbow Dash, knocking her out of the air. Rainbow let out a loud, startled "Oof!" as she hit the ground hard. "What the—? Scoots?!"
Scootaloo lay sprawled on Rainbow's belly. Her mane, tail, and feathers were singed and smoldering; a few small flames were still burning on her tail.
"EEK! FILLY ON FIRE!" Pinkie screamed, pulling a fire extinguisher out of nowhere and dousing both Scootaloo and Rainbow with a liberal amount of foam.
"Oh my goodness!" Fluttershy gasped, covering her mouth with her hooves. "Scootaloo, what happened?!"
Scootaloo rubbed the back of her head dizzily. "The merry-go-round broke down," she mumbled listlessly. "Made the darnedest sound..."
A herd of fillies and colts stampeded toward them, led by Cheerilee. "Scootaloo! Are you alright?"
Scootaloo blinked and looked around. "Huh? Oh, uhh...yeah, I'm okay," she said. She flapped her soggy wings and looked down at Rainbow, who was covered in foam. "Umm...sorry about that," she said.
"No...problem," Rainbow said, sputtering and spitting out foam. "What the hay happened?"
Diamond Tiara laughed. "The Goofsaders tried to blow up the school," she said.
Fluttershy's eyes widened. "What?!"
"We did NOT!" Apple Bloom protested.
"This is all my fault," Cheerilee said shakily. "Time Turner gave me a make-your-own-fireworks kit, and I thought it'd be a fun chemistry lesson to show the class how you..." She trailed off, then facehoofed. "What was I thinking?!"
Pinkie gasped. "You let these three anywhere NEAR gunpowder?!" she shrieked, waving her hooves at the Cutie Mark Crusaders. "Are you loco in the coco?!"
"Apparent...ly..." Cheerilee trailed off as she stared at Sonata. She wasn't the only one; a lot of the students were watching Sonata float lazily in the air, expressions of fear, wonder, and curiosity on their little faces.
Sonata, for her part, had caught on to being the center of attention, and was smiling and waving. "Hi!"
"Class?" Cheerilee said. "I think we'll change the lesson plan for the afternoon. Pinkie Pie, Rainbow Dash, Fluttershy, why don't you teach the class a little something about...whatever your friend here is?"
