Duncan was sitting on the front steps of his house as he eagerly waited for the mailman to show up, he wasn't going to prank this time, this time, it was serious. Cindy was letting Sledgehammer get some exercise and they couldn't help but notice the delinquent boy.

"Hmm... I wonder who Duncan's waiting for?" Sledgehammer pondered.

"Hey, Duncan, what's going on over there?" Cindy called out.

"Huh? Oh, hey, Cindy, hey, Sledge," Duncan replied. "I'm waiting for the mailman."

"That's the biggest news I've ever heard of," Cindy commented. "Duncan Nelson not pranking the mailman."

Duncan rolled his eyes slightly. "Yeah, yeah, yeah..."

"So, what's going on?" Sledgehammer asked.

"I'm expecting mail from Dusk." Duncan smiled proudly.

"Dusk, huh?" Cindy replied.

"That's right." Duncan confirmed.

"Dusk is the red one, right?" Sledgehammer asked.

"No, Dusk wears green," Cindy said. "What about her anyway?"

"After our last meeting, she said she'd let me and some friends come see the taping of their newest music video," Duncan said. "Too bad I can't bring Abby though, but Mom took her and Janet to the spa this weekend."

"Oh, oh, take me, take me, please!" Cindy begged.

"Whoa! You wanna go somewhere?" Duncan asked.

"Well, yeah, it's been pretty boring for the past couple of days." Cindy admitted.

Duncan chuckled. "Good girl... I know I'll bring the Mystery Inc crew."

Cindy nodded to that.

Ami and Yumi were walking down the street together.

"Man, that was a lot of homework..." Yumi groaned. "I don't know how we'll ever get our schoolwork and upcoming gigs balanced together."

"I know what you mean," Ami agreed. "I think we need a vacation."

"Konichiwa, Ami," Cindy greeted. "Konichiwa, Yumi."

"Hey, kid," Yumi replied. "What's up?"

"You guys look stressed." Cindy noticed.

Ami yawned. "Homework and Kaz..." she then muttered wearily. "I don't even have enough time to see Ash and Pikachu."

"Or Finn for that matter." Yumi added in.

"Sounds like you guys could have a break, and-Hold that thought." Duncan said before looking to see that the mailman was coming and he ran over to him.

"AAAAUGH!" The mailman panicked. "DUNCAN NELSON!"

"Wait, wait, wait!" Duncan told him.

"Just take it! Take it and go away!" the mailman threw the mail at him and then ran down to his other block.

Duncan then sighed and he picked up the mail. "Bill, bill, bill, bill... HA! Yes!" he then took out the letter from Dusk. "Whoo-hoo! Alright!"

"Guess that must be from Dusk." Cindy smiled up to Sledgehammer as he borrowed in her hair.

"It is." Duncan told her.

"What does it say?" Cindy asked.

"Oh, just usual stuff..." Duncan hid away the special letter from Dusk personally. "The girls all recommend that we bring Mystery Inc along if anyone else."

Sledgehammer snickered as he swiped the love letter from Dusk.

"Well, there's two people who also want to come..." Cindy said.

"Ami and Yumi." Duncan and Cindy then said together.

"It would be nice to listen to other music that isn't our own." Ami admitted.

"Yeah, we're awesome and all, but I could use a break from being me for a day." Yumi chuckled.

"Isn't that every day?" Duncan joked.

"Watch it." Yumi warned.

"I'll go as long as Sledge goes too... Sledge? Sledge!" Cindy replied.

"'Dear Dunky Wunky, I looooove you'!" Sledgehammer teased.

"Hey, give that back!" Duncan snarled.

Sledgehammer snickered.

Cindy grabbed her possum by his tail and then gave the letter back to Duncan. "Sorry about that, Dunky Wunky-Erm, I mean Duncan."

"I'll tell Mystery Inc to come in a group text." Ami said as she took out her cell phone.

"Is there anyone else you want to invite?" Yumi asked the delinquent boy.

"Yeah, Sarah." Duncan joked.

"HA! Good one..." Yumi scoffed. "Just keep Lightning away from me."

"I think he's with Ellody right now anyway..." Cindy shrugged.

"Where's the music video being filmed in?" Ami asked.

"Fortescu Castle." Duncan replied.

"I think I heard of that place before." Yumi pondered.

"Really?" Ami asked. "It sounds like when we met the Talent Suckers."

"No, no, not from there..." Yumi said. "Hmm... Well, I'll think about it."

"It's gonna rain later tonight, Mystery Inc says that if you guys want, we can go tonight or wait tomorrow." Ami said.

"It doesn't matter to me," Duncan shrugged. "Whatever works best."

Ami then continued to text. "Tonight it is."

"The sooner Duncan sees Dusk, the better." Sledgehammer teased.

"Oh, shut up." Duncan scolded as everybody else laughed with the pink possum.

Duncan growled at them.

Later on, Cindy was making a sandwich to get ready to leave later tonight. "I finally get to go on a trip," she said to herself. "It's been so boring for the past couple of days."

"How boring was it?" Sledgehammer smirked.

"See? You're so bored that you're hanging around me more than usual." Cindy told him.

"I know," Sledgehammer agreed. "I picked on Kevin so many times that it's not fun anymore."

"Which is why we could use a fun weekend." Cindy nodded.

Penn poked his head in, he then pouted and walked away so he wouldn't bother Cindy.

"Hmm... Should I bring something?" Cindy wondered.

"Your water?" Sledgehammer asked.

"Come on, let's go to the room..." Cindy said as she then ate her sandwich and walked to her room as Sledgehammer scampered and sat on her shoulder.

"So, how many days are we going to be there?" Sledgehammer asked.

"I'm not sure, hopefully not too many, you know how my mother worries." Cindy replied as she took off a piece of her sandwich to give to him.

"Tell me about it," Sledgehammer scoffed. "She cries even if you're gone for five minutes."

Cindy giggled a little as she then came to her room.

Penn came in the room and cleared his throat as Cindy was on her computer. "Erm... So, Cindy, going out?"

"Yeah, I'm going with Duncan, Ami, Yumi, and Mystery Inc to go visit the Hex Girls." Cindy replied.

"Why?" Penn asked.

"Because Duncan invited me." Cindy said.

"Oh... Okay..." Penn said. "You bringing someone with you?"

"Uh-huh." Cindy nodded.

"Yeah?" Penn grinned.

"Sledgehammer." Cindy then said with a smile.

"Oh..." Penn pouted.

Sledgehammer laughed in response.

"Sorry, Penn." Cindy apologized.

"Okay..." Penn said as he stared at the floor and walked away.

"Bye!" Cindy waved and then went back on the computer.

"Whatever." Penn scoffed.

"Now, where was I? Oh, yeah." Cindy remembered.

Meanwhile...

Brianna and Trent sat on a porch swing together until the Mystery Machine would come pick them up.

"It was nice of Duncan to invite us." Trent said.

"That's something you don't hear everyday." Brianna said with 'nice' and 'Duncan' in the same sentence.

"And it'll probably be the only time I say it." Trent replied.

Brianna and Trent laughed together.

On the Puffy Bus...

Ami and Yumi were finishing up their homework.

"You girls would not have to worry about homework if you let me hire you a tutor instead of going to a school," Kaz told his clients. "You are rock stars, not normal teenage girls!"

"We'll be fine, Kaz, besides, we're going away for a while." Ami said.

"WHAT?!" Kaz flipped out.

"Well, that Math's done, how's your end, Ami?" Yumi asked.

"Could you pass our copy of the Periodic Table?" Ami held out her hand. "I always get those gases mixed up."

"Sure." Yumi replied as she handed her the paper.

"You're going on vacation?!" Kaz gaped at his clients.

"You won't even know we're gone, don't get a crab in your pants." Yumi glared.

"It'll be okay, Kaz," Ami soothed before thinking. "Hmm... Do you think we should bring the cats? Every time we leave them alone with Kaz, he just gives them trouble."

"Scooby hates cats and Cindy's afraid of cats, remember?" Yumi reminded.

"Oh, yeah." Ami said then.

The cats nuzzled up against Ami and Yumi.

"It'll just be a short visit, they'll be fine..." Ami smiled as she pet her fluffy white cat.

The cats then smiled evilly to Kaz who gulped to them in response.
