"Scoob next time I'm picking the hiding spot." Shaggy says having not wanted to be going into the water.
"Sorry." Scooby says.
"Hang on folks. Once the magnetic arm releases us big splash down!" Fred shouts as the arm then releases the sub into the water.
"Wow. I've never been under water like this before." Alexis says looking out the window.
"This is great. All it needs is a styling green paint job and it'll be the bomb digaty." Fred says.
"It even has a sonar activated camera." Velma says messing with the camera.
"Activating exterior lights." Shannon says as she turns on the lights.
"Now all we need to do is find the under water entrance to the caves." Fred says as they start searching.
"It's darker down here than I thought it would be." Daphne says as Scooby looks out the window.
"Monsters! Monsters!" Scooby says getting scared by something and jumping onto Fred.
"Look out Scooby!" Fred says as he tries to steer the sub.
"It's only a school of eels Scooby." Alexis says.
"Fred watch where your going." Daphne says as Fred wildly steers the sub.
"I would if I could." Fred says not able to see because of Scooby.
"I think we found the entrance." Shannon says.
"Really?" Fred asks.
"Really?" Scooby asks.
"It is the cave." Velma says.
"And I thought it would be impossible." Shannon says shocked.
"Well nothing's impossible when you got Scooby Doo around." Daphne says.
"Aww shucks." Scooby says as he laughs.
"Is it my imagination or are we in shallow water? Prepare to surface" Fred says as he brings the sub to surface.
"Wow this place is huge." Alexis says as they open the hatch and see they are in a giant cave.
"Hello." Fred says his voice echoes while they get out onto land.
"Please don't do that Fred." Shaggy says.
"Why not?" Fred asks as he helps Alexis and Daphne onto land.
"I'm afraid something might answer." Shaggy says nervously.
"You guys might wanna check this out. It looks like Scoob found where Nessie tosses her left overs." Shaggy says as he and Scooby find something while the others come over.
"I think we've stumbled across a burial ground. Used by ancient Scottish warriors." Velma says seeing the skeletons.
"Well if they buried their dead down here than that means there must be a secret entrance somewhere leading up to the surface." Alexis says.
"Hey guys check us out we're a couple of brave warriors." Shaggy says as he and Scooby are dressed up in armor holding swords.
"Reah." Scooby says as he and Shaggy play around.
"Hey gang take a look at this. It's a screwdriver but what's it doing down here?" Velma asks as she finds a red screwdriver.
"Maybe they were handy ancient people." Fred says.
"Freddy." Velma says annoyed.
"What?" Fred asks.
"No offense Fred but even if that were so this screwdriver is in very good condition to be that old." Alexis says.
"What would ancient warriors be doing with a modern screwdriver?" Velma asks.
"Uh guys if you think that's fishy just look behind you." Shaggy says as the group turns around and sees the monster as it snorts at them.
"Jinkies!" Velma shouts.
"Get to the submarine." Fred says.
"Shaggy! Scooby! Come on!" Alexis shouts as they run for the submarine quickly making it into the submarine as they take off back under water.
"The creature is following us!" Velma says looking at the scanners.
"Like take the picture Velma and let's go home." Shaggy says scaredly.
"We can't. The sonar camera is mounted on the front of the sub." Velma says.
"We'll have to turn around if we're gonna do a photo shoot." Daphne says as they keep going with the Loch Ness monster right behind them.
"Head straight up that canyon wall." Velma says as Fred goes up the wall.
"We just lost our port side sensor." Alexis says.
"Careful Freddy." Daphne says.
"Sorry." Fred says as he tries to steer.
"Twenty five more meters. It's a straight shot to the surface." Velma says as they head for the surface.
"Watch out Fred!" Alexis shouts seeing the creature coming right at them.
"I see it!" Fred says steering the sub only to get hit by the tail causing them to hit a wall and loose their camera before heading back toward the surface.
"She's gonna ram us!" Velma says seeing the creature right behind them.
"Hang on!" Fred says as the creature rams them out of the water and into the air.
"Like who knew you could get air sick in a submarine." Shaggy says as they get caught by the magnetic arm.
"That was close." Alexis says as everyone sighs in relieve.
"Like now can we go home?" Shaggy asks.
