Guardians Of Harmony: Adventures In Canterlot City

It was a fine day at the Equestria Fair, where everyone was having a good time playing games and enjoying the attractions. Rainbow Dash excitedly led Applejack and Sunset Shimmer to the newest ride at the fair.

"Come on, guys," Rainbow Dash urged.

"Why are you so excited, Rainbow?" Sunset asked.

"Because they've got an amazing new ride—the Furious Flyer Train," Rainbow said happily. "I saw them testing it earlier. It was so fast; it's going to feel like flying."

"It seems you're not the only one who wants to ride it," Sunset joked, noticing the long line of people.

"Everyone, the Furious Flyer Train is... gone!?" a voice announced, surprising the crowd.

"It can't be gone; trains don't just disappear into thin air!" Rainbow exclaimed.

"True, but the track is a closed circle. How could it get off and keep going?" Applejack wondered.

"AHHH! LEAPING LAB!" someone shouted as a mobile lab came out of nowhere and rolled away.

"What in tarnation was that all about?" Applejack asked, still in shock.

"Yeah, it looks like Melvin's Lab, but it's all over the place. Maybe he's behind it," Sunset suggested.

"Good idea. Besides, that slimy toad is always up to no good with his wacky inventions."

Then Sunset's phone rang.

"It's a message from Twilight," Sunset said, looking at her phone.

(If you're reading this message, Fluttershy, Rarity, Pinkie Pie, and I have started looking for the train.)

"Come on, we better help the others."

With that, Rainbow Dash, Applejack, and Sunset transformed into their crystal guardian forms and began their search for the missing train.

Meanwhile, Sci-Twi, Pinkie, Rarity, and Fluttershy were in hot pursuit as they found the train and the person driving it.

"MELVIN!?" Twilight, Pinkie, Rarity, and Fluttershy shouted.

"Well, hello, Rainbooms!" Melvin greeted them.

"Applejack and the others just saw you driving your lab," Rarity said.

"That wasn't me. No one was driving my lab. The blasted thing short-circuited and took off. Good thing I've got this super-fast train to catch it, eh?"

"But where did these train tracks come from?" Fluttershy asked.

"Easy, thanks to my invention—the Tracker Whacker. It makes tracks anywhere."

"Wow! That's kinda cool!" Twilight mentioned.

"And what's even cooler is the other one at the back picks the tracks up again."

"Why do you need this train? Let us help you get your lab back!"

"HA! Like I'm giving up this train once I get my lab! No way! With the tools from the lab, I can make this train even faster. Making me the fastest villain in the world! Huh?" Melvin looked at his screen. "A-ha! There you are, my lab. Love to stick and chat, but I've got a lab to catch. Mua-ha-ha-ha!"

"Why that big meanie!" Pinkie said angrily as Rainbow Dash, Applejack, and Sunset caught up with the girls.

"Hey, guys. Sorry for the delay," Rainbow said. "We had to make sure that people stayed clear of Melvin's lab."

"Speaking of that, where is that slimy varmint?" Applejack asked.

"Well, Melvin stole it so he could catch his lab. Now we have to stop him before he makes the train even more dangerous and puts people in danger," Pinkie Pie said, eating a cupcake.

"On it!" Rainbow used her speed to catch up with Melvin.

"Oh, for the love—" Applejack sighed. "Why does she always run off beforehand?"

"Allow me." Twilight used her magic to teleport herself and the others to Rainbow and Melvin's location.

Meanwhile, Melvin was closing in on his lab.

"Ha-ha! I've almost caught up with you, naughty lab!" Melvin looked left and right for the Mane 7. "And no sight of those pony girls. It doesn't even matter if they catch up to me!"

"That's what you think, Melvin!" Rainbow was on top of the train. "Let's do this!"

As Rainbow Dash made a jump to the front of the train, a strong draft blew her off. She was caught by Rarity before crashing into a tree branch.

"Thanks! I was almost bird feed!"

"No need for hasty actions, Rainbow. We'll get there and stop him," Rarity reassured her.

"Ooh, I got an idea! Let's sneak up on him really slowly!" Pinkie suggested.

"Why be slow? Let's just go!" Rainbow urged as she fell off the train, causing Melvin to gasp.

"Huh? Those pony girls couldn't be on my train, could they?" Melvin thought to himself. "Better make sure they're not!"

Melvin shook the train, hoping to shake off the Mane 7. They held on for dear life.

"Sorry, guys!" Rainbow Dash flew back to the gang. "Looks like Melvin found out we're on the train."

"It's OK. New plan—we all go after Melvin at once," Sunset said. "He can't stop all seven of us!"

"Right!" the Mane 6 cheered happily.

"Okay! On three! One... Two..."

"Come on, guys!" Rainbow Dash yelled as she jumped ahead.

"Wait! Rainbow Dash!" Fluttershy shrieked.

As Rainbow jumped on the passenger car, a blinking monitor screen grabbed Melvin's attention. He pressed a button to activate a robot arm that captured her. She tried to escape, but it held her tightly.

"Why didn't I listen to the others?" Rainbow wondered to herself. "Melvin's almost caught up with his lab, and it's because I rushed."

Then her friends appeared.

"Rainbow?!" Pinkie exclaimed.

"Are you all right?" Twilight asked.

"I'm okay," Rainbow said with remorse. "But I'm so sorry. Every time you guys had a plan, I rushed ahead without you, and it didn't work."

"It's okay," Rarity reassured her. "You were just really excited about the train."

"I'll take care of this robot arm," Applejack said as she ripped the arm off with her strength, freeing Rainbow.

"Thanks, AJ," Rainbow thanked her. "But now I've got a plan!"

Then the train horn went off as Melvin turned around.

"I know you're in there," Melvin smiled. "But not for long!"

Melvin shook the train even harder.

"Quick! What's your plan?" Sunset asked Rainbow.

"We're going to stop this train for good," Rainbow responded. "And we're going to do it together. Twilight, you grab some branches and pass them to me. Rarity, you and Applejack get close enough to the Tracker Whacker. Then I'll fly the branches to you, Applejack, and you can use them to jam it and stop the tracks. Without tracks, this train won't ever catch Melvin's lab."

"I like it!" Pinkie said happily. "Let's do this!"

Melvin gasped as his lab came into range.

"Okay, my Tracker Whacker, more tracks! More tracks!" Melvin's Tracker Whacker made more tracks.

Twilight levitated some branches from the ground. She gave the signal, and Rarity and Applejack moved into position on opposite sides of the Tracker Whacker. Twilight passed the branches to Rainbow, who then flew up and passed the tracks to Applejack, who caught them.

"Nice one, RD!" Applejack praised her, catching Melvin's attention.

"What!?" he exclaimed. "Stop it, you fools!"

"Too late for that, geek. AJ, Rarity, do it," Rainbow said.

Applejack stuck the branches into the Tracker Whacker while Rarity used her gems to block it.

"NO!" Melvin screamed as the Tracker Whacker started to go on the fritz. The train shook violently. But the girls held on to the side of the train.

"Whoa!" Fluttershy used her spirit form, showing an astral image of a gecko, allowing her to stick to it.

"Hang on to me, everyone!" she urged the others.

Sunset, Twilight, Rainbow, Rarity, and Pinkie grabbed hold and yelled in unison. The train turned a corner, and Applejack saw her chance, warning the others to get off.

"I got this!" Applejack stopped the train in its tracks.

Melvin got off and started to groan. "Huh?"

"*Giggles* See, Melvin. We told you we could catch your lab," Pinkie said as the lab came to a complete halt.

"My lovely lab! Yes! Yes! Yes!" Melvin said happily as he kissed his lab. "I might have lost my train, but I'll always have you, my lovely lab!"

"Now, let's get this train back home," Twilight said.

"Everyone is going to be so happy!" Pinkie said happily.

"I'll get you next time!" Melvin shouted as he rolled away in his lab.

"My word!" Rarity exclaimed. "He didn't even say 'Thanks for helping!'"

"Don't worry, Rarity. We managed to get the train back. Besides, I don't think this is the last time we'll see him," Sunset reminded her.

And so, the Mane 7 were able to get the train back on track and stop the mad scientist.
