Every four years, the Bonkerton Comet would arrive at Peaceville, causing very strange things to happen with each flash. But last year, something even stranger happened. For you see, the comet was briefly knocked out of orbit that year, and that small incident would lead to the biggest change in all of Peaceville history.

It all started when eleven-year-old demon spawn Corey Riffin was hanging out in the garage with his three friends, Laney, Kin, and Kon. They had yet to form Grojband, so they were still normal kids in a normal town. They did rather unusual things together. Today's activity? Testing out Kin's new time machine.

After a few hours, Kin stepped out of the machine, causing Kon to gasp in delight. "One million BC and back again without messing up the future one single bit!" the smarter twin announced. He presented a small lemon tree. "Who's in for victory lemonade?"

Corey, Laney, and Kon were confused. "Why Kin, I've never heard of 'lem-o-nade'," Kon remarked.

Kin gasped and looked at the lemon tree. "NOOOOOOOOOOOOOO!"

At that moment, Trina showed up. "Can you keep it down?!" she asked. "I totally can't here myself think!" She didn't normally use those words, but she spoke like that as an attempt to blend in with the humans, thinking all human teenage girls spoke like that.

"Sorry Trina," Corey replied. "We're just testing a new time machine."

Trina rolled her eyes. "Whatev's," she said. "Just stop being, like, all noisy. Mina's out sick and I want to work on my plan to captu- I mean, become boyfriend and girlfriend with Nick Mallory." She grinned, not wanting her cover to get blown.

"Did I hear you say 'capture'?" Corey asked, making sure he didn't hear things.

"NONE OF YOUR BUSINESS!" Trina shrieked. Then she left the garage, slamming the door shut.

"That was strange," Kon said.

"Come to think of it, you two have been acting strange," Kin told Corey. "Is there something you're not telling us?"

Corey didn't know how to respond to that. He was trying his best to blend in with the humans in Peaceville ever since he first set foot on the surface world. Trina has also tried to blend in, but due to her powers, she wasn't doing a good job. At least he became friends with three humans.

"Um... You see... I..." the younger demon stammered. Then he came up with a perfect excuse. "Why don't we sell free kittens in the mall parking lot? We finished the time machine quickly, so there's still plenty of daylight left."

Laney, Kin, and Kon looked at Corey. "Sell free kittens?" Laney asked. "How could we sell them if they're free?"

"Don't worry about logic, Lanes," Corey said, putting an arm around her. "Let's just do it!"

That evening, Corey and Trina were eating dinner with their mother. Both siblings didn't look happy as they ate. Who could blame them? They both had bad days today.

"So, how's my children doing?" Mrs. Riffin asked with a smile.

"Terrible," Corey quietly said. "I helped my friends sell free kittens in the mall parking lot. It was going well, but we didn't make any money."

"Sweetie, that's what free means," Mrs. Riffin explained.

"I had no other choice!" Corey exclaimed. "They were starting to get suspicious and I had to distract them."

"By making them do an oxymoron?" Trina asked.

"Okay, so it wasn't a good idea," Corey admitted. "It's better than having them find out I'm an electrical-powered half-demon from the Underworld."

"At least you can control your powers," Trina said. "I have to use my soul capture device to make sure I don't accidentally cause a volcano to erupt!"

"You're lucky you have more powers," Corey said. "They're why you're dad's favorite. He thinks that just because you can summon a pillar of flame by snapping your fingers, you're more qualified to becoming the next ruler of the Underworld."

"But I still want to be the first demon to join the RIPD," Trina said. "I just wish I could control my powers."

"Not as much as I wish I had stronger powers," Corey said.

That night, as Corey and Trina slept, something strange happened. The Bonkerton Comet was visible above Peaceville. Just as it went back into orbit...

FLASH!

As the comet left, Corey and Trina squirmed in their sleep. Trina gripped Mister Mooseface as her ivory claws appeared, while Corey moaned as his four extra arms emerged. Then suddenly, a strange presence rose in the air as their horns, wings, and tails appeared. Their skin and hair changed, and their teeth became sharp fangs.

Then all was quiet. At least until tomorrow...
