"How much of your equipment is missing?" Drell asked.
"Well, you see, a couple of weeks ago, we noticed that some sonar equipment had gone missing from the Marine Biology Center." Jessica informed as she walked with her guests.
A killer whale hopped from the water beside them and made a big splash.
"Sounds important." Patch said.
"A few days later, an RV disappeared from the Motorsports Pavilion." Jessica then showed.
There were two campers on motorcycles which rode up over a couple of ramps and high-fived each other as they rode and did an X-Treme dangerous stunt like on TV.
"Now they're just showing off." Fred scoffed.
"That is so awesome!" Mo cheered.
"Most luxury RVs have GPS locators built in," Velma looked thoughtful before taking out a handheld device. "I'll ping the area to see if it's sending out a signal."
"Great." Mo smiled.
Velma then went to work to track down the missing RV.
Jessica took a look. "That's right in the middle of Shadow Canyon."
"Shadow Canyon?" Burt replied. "They say that place is haunted by the ghost of a lost hiker, still searching for her way out, they call her 'The Specter of Shadow Canyon'. Legend has it if you can hear her terrifying wail, you're a goner."
Scooby gulped and shivered in response.
"Dude, I did not need to hear that." Shaggy added in nervously.
"We'll need to split up." Atticus said.
"Hey, that's my line." Fred said.
"Does it really matter at the moment?" Mo asked.
"Whatever..." Fred sighed.
"Hold on, let me get this straight," Deacon spoke up. "There's a crazy man with an axe in the woods, a ghost in the canyon, a fish monster in the water, and you guys wanna split up and look for clues?"
"Yeah, that's right." Atticus and Mo nodded.
"I'll take the lake," Fred said. "I wanna check out that building Scooby and Patch saw. Who's with me?"
"I'll go," Jessica came behind him with a flirty smile. "I'm a certified scuba instructor."
"I'll go too." Atticus said.
"Count me in." Luke smiled.
"Count me in too." Daphne said, not wanting Jessica alone with her man.
"Then the rest of us will head to Shadow Canyon." Velma stated.
"Oh, no." Scooby disagreed.
"Like, you can forget it," Shaggy added in. "Every time someone tells a campfire story, it comes true. Scooby-Doo and me are trying to live a Specter free lifestyle here. You can find us in that five-star dining hall when you get back."
"I'd actually like to go with Atticus to see that town underneath the lake as well." Goku said.
"Sounds good," Velma said, then looked to Shaggy and Scooby. "Guys, maybe you should take Deacon with you, he seems a little freaked out."
Deacon seemed to be using his inhaler more extensively now than he ever had before with these monsters ruining his summer vacation.
"I agree." Colette said.
With that, they all split up. Cherry was hiding behind a tree as she watched Drell once more.
"That girl is up to something." Drell said.
Jessica took the ones going to the lake on her speedboat, which were herself, Atticus, Fred, Daphne, Luke, and Goku.
"Alright, here we are," Atticus said once Jessica stopped in the center of the water as Fred and Luke were getting their scuba gear together. "Alright, now all we have to do is dive down." Atticus said.
Fred nodded, then looked to the younger boy with them. "Luke, if the Fishman surprises us, I'll catch him with this net launcher, so there's no reason to be-"
Luke put on the scuba gear and dove into the water with no hesitation or nervousness.
"Afraid..." Fred then weakly finished.
"You okay, Fred?" Atticus asked.
"I guess so..." Fred sighed. "It's just... How am I supposed to be his mentor if he never listens?"
"Don't worry, Freddy," Daphne smiled, putting her hands on his shoulders. "You'll get your chance."
"She's right." Atticus smiled before diving into the water with Goku.
Jessica, Fred, and Daphne then swam after them. And where they were surprised to see that Atticus was a merperson as well.
"Come on, guys." Atticus said casually.
Goku nodded before swimming along side his student/apprentice.
Luke spotted the underwater city and gestured for the others to come where he was. They all did so to get a better look. They swam past the flowing seaweed as there were hidden glowing yellow eyes watching them. And where Daphne seem to have noticed while Atticus and Goku noticed it as they sensed something below them.
Darla and Amber were walking together as Velma, Mo, Trudy, and Burt were riding around in a jeep together to track down the missing RV.
"I really missed you too, Darla," Amber said. "I really wish you could've come with me."
"Same here." Darla said as she brought Amber with her as they snuck on board inside the jeep where no one would see them.
"Shh..." the two little girls shushed each other as they hid inside the jeep after it took a quick stop.
"Did any of you hear something?" Mo asked.
"Just the sound of my internal thoughts wandering away as I continue to waste my time." Trudy pouted.
"Never mind I must be hearing things let's just keep going." Mo said.
"I agree." Colette said.
"Okay, let's go." Velma said as she plugged in her device to track down the RV.
"And away we go." Patch smiled as he and Colette came along.
Colette smiled as she leaned against Patch with a dreamy smile. Patch smiled back to her as they rode off.
"Oh, no," Velma frowned as soon as her device instantly shut off on its own. "We lost signal. Now what?"
"Well, what if we go out and try to see if we can find any tire tracks?" Patch said.
Trudy looked mildly annoyed with the nature animals among the trip, such as buzzing gnats and chomping squirrels. She looked curious to the squirrel however and hopped out of the jeep to follow it, and found tracks in the gardens.
"I think Trudy found them." Colette said.
"Cool." Patch smiled.
"Good eye, guys." Velma smiled as she looked to see where the tracks led.
They got back into the jeep and drove it through the tire tracks. And where Velma looked through the mirror to see Trudy smiling, telling her that she was enjoying this.
"Our first road trip together..." Colette said to Patch.
"The first of many." Patch nuzzled against her.
"Awww!" Two little girls' voices said.
Patch and Colette parted and could've sworn they heard that.
"You guys hear something?" Trudy asked the puppies.
"Yeah, it sounded like it came from back here." Patch said, pointing to the blanket behind them.
Colette sniffed the blanket and sneezed slightly. "I smell strawberry shampoo."
"Wait, Amber, is that you under there?" Patch asked.
"Umm... No?" Amber lied.
Patch and Colette narrowed their eyes. Trudy, with narrowed eyes as well, pulled the blanket to show Amber and Darla. The two little girls felt exposed and smiled nervously and shyly waved as they were revealed.
"What are you two doing here?" Colette asked.
"Uh... What are you two doing here?" Darla replied.
"Nice try, Darla." Patch said.
Darla then pouted.
"We're sorry, but we wanted to help." Amber admitted.
"Well, we might need all the help we can get." Trudy said.
"So we can stay?" Darla asked.
"You can stay, just stay out of trouble, little ladies." Burt warned.
"Yes, sir." Darla and Amber promised.
"Alright then, let's keep going." Mo smiled.
Darla and Amber smiled as they were apart of their very own adventure while away on summer camp.
