Fred awoke at 8:00 to the sound of sizzling meat in the kitchen, where Uncle Tex was cooking cowasaurus steaks and dodo eggs. Wilma usually made Fred's breakfast for him, whether it happened to be two dodo eggs over easy or a bowl of Post Pebbles cereal that Barney always kept stealing; but today, Tex prepared a surprise for his nephew.

"Oh, Uncle Tex, you didn't have to!" said Fred.

"Who else do I have, Fred?" Tex asked. "If you guys weren't here, it'd be just the cowasaurus herd and me." He wished not to make Fred cry by mentioning Edna, Fred's mother and Tex's sister, who was killed in a car crash when Fred was fifteen; and he could never forget when his own wife, Helen, drowned in the Rio Petrificado despite the efforts of their son, Hermanaric, to save her when their canoe had overturned.

"You have a good point, Tex," said Barney as he came down. "My parents moved to Las Piedras when they retired, but when I cry about them, I know that they're still with me in my mind and heart."

Tex woke Wilma and Betty by clanging his triangle. "Morning already?" asked Betty.

"Beats waking up to Fred pounding on the door at 10:30 at night," groaned Wilma. "He never got a minute's rest with our saber-toothed tiger around."

After breakfast was over, Fred and company waved goodbye to Uncle Tex and set off on the next leg of their adventure. They were almost to Rock Vegas when Dino saw some suspicious people behind them. Hoping to escape pursuit, they went to Stonewood Bar and Grill for some lunch.

"I feel like something nasty is about to happen," said Wilma nervously, but nothing suspicious happened until after they had finished. Fred was paying for their meals when he heard a scream. When he turned around, he saw two men carrying Betty with Wilma and Barney both in pursuit.

"I can't believe that those fiends have run off with Betty," Barney said. "If they knew any better, they'd kidnap you, Fred."

"She knows something that we don't," said Fred. "I can feel it."

"I'll follow that car," said Wilma. "I have plenty of money for a taxi."

"And we'll cut to the chase!" cried Fred. "Come on, Barney! We gotta get Betty back before it's too late!"

"Taxi!" cried Wilma as a cab pulled up. She jumped in and shouted "Follow that car!"

"Which one, madame?" the driver queried.

"There's a black Brontosaurus," said Wilma, "licence plate WHJB60. It's driven off with my best friend!"

"You've got it!" cried the driver, and away they went! In his rear-view mirror, he saw Fred and Barney. "Are those men following us for a reason?" he asked.

"Yes," replied Wilma, "but don't expect them to chase _us_. They're both on our side."

"One of them looks just like my brother," said the driver. "You know, the one with blond hair."

"Dusty?" questioned Wilma. "Is that you?"

"Oh, yes," said the driver, "and you must be Wilma."

Behind them Dino barked loudly, hoping to attract Wilma's attention. The black limousine was escaping, and it seemed as though all would be lost.

"The Brontosaurus is getting away!" shouted Barney. "Faster, Fred!"

"Are you bonkers, Barney?!" cried Fred. "I might kill all five of us – and that includes Dino!"

"I'm absolutely serious, Fred," replied Barney. "We should explain what to do to the driver of the cab."

Fred pulled up next to the cab at the traffic light that had just turned red. It was at this point that yes, the cab's driver was indeed Barney's younger brother, Dusty Rubble.

"He's quite far ahead, Barney," said Dusty. "What should I do?"

"Just keep following him," said Barney. "We'll meet up with you later."

Fred saw a Radiosaurus Center and came up with a plan. "We'll get something to better communicate with Wilma and Dusty," he said, "and then we'll find out what they're up to."

Fred and Barney went in and got some walkie-talkies before taking off. By this time, both Dusty and the Brontosaurus were very far ahead, but they knew that quitting would get them no farther, so they still "followed that car."

Fred and Barney met up with Dusty and Wilma at a hotel in the Rock Vegas suburb of Little Stone Mound. "We've found the hideout, guys," said Dusty, "but they've got two massive guards who won't let us in. What will we do now?"

"Just find out what the password is if there is one," said Fred, "and we'll contact you through the walky-talky."

"We need to find a way to get in," said Barney, "and simultaneously stay out without being noticed. The problem is how we'll do it."

"If only we had some kind of costume store around here," said Fred. Then he noticed across the street exactly what he expected: Pterodactyl Tailor and Costumes, a famous nationwide chain of costume stores.

"Alright," said Dusty. "It's disguise time."

Fred and Barney went across the street to Pterodactyl Tailor and got some costumes for all four of them. Dusty was disguised as a mobster and Wilma as his moll; but when Dino saw them, he made a weird squawking noise, signifying confusion.

"Who are you two supposed to be?" asked Dusty when he saw Fred and Barney in disguise, more about Dino's confusion than his own query. Fred was dressed as some kind of mad scientist and Barney as a sophisticated gentleman in a tuxedo.

"Dr. Henry Lithippos, mobster scientist," replied Fred.

"Lord Albert Steinheist, underground drug smuggler and millionaire," added Barney.

"Oh, don't worry about it," said Wilma. "Let's go in, Rocky Stoneman."

"You got it, Frau Wolfenstein," said Dusty.

Wilma and Dusty went up to the two bodyguards. "What's the password?" one of them asked.

"The boss sent me," said Dusty nervously.

"We allow both of you entry," said the other bodyguard.

Wilma and Dusty went down to the basement, and they both appeared terrified. Betty was tied to a chair and a poorly tied handkerchief covered her mouth.

Dusty turned on the walkie-talkie. "Stoneman to Dr. Lithippos and Lord Steinheist," he said. "We have found the victim."

"Good job, Stoneman," said Fred, carefully avoiding to use any names that would blow their covers. "What is Frau Wolfenstein up to?"

"She is releasing the victim from her prison," said Dusty. "We must get her out safely."

"Lord Steinheist to Stoneman," said Barney. "I feel like we're being watched."

"We'll get the victim out if it's the last thing we do," replied Dusty. "She is now free, so we're heading out."

The three of them ran out quickly, but when they got outside, the bodyguards came after them. Betty recognised them as the men who kidnapped her.

"Hold it!" cried Dusty, pulling a prop machine gun out of his trench coat and aiming it at each thug alternately. "I don't care if the bullets are real or fake, but I'm not afraid to fire!"

The two thugs ran off, completely ignoring that Fred and Barney were watching them. "Police!" cried Fred as the thugs turned around the corner.

A policeman with a custody helmet came up to Fred and Barney. "You'd best not be fooling me with those disguises," he sneered.

"We most certainly are not," said Fred. "You might not have seen them, but two thugs ran off into the distance."

"How do you know about those two?" added the policeman.

"They kidnapped my wife and tied her up," replied Barney. "They just headed past the theatre."

"I'll get them," said the policeman. He caught them less than five minutes later, thanking Fred and Barney as they drove away.

As they were about to leave, Wilma paid Dusty twenty clams for cab fare and another thirty for saving Betty. With all five of them reunited, they could get back to their adventure.

"Thank goodness I'm safe with you guys!" sighed Betty. "What's next, Fred?"

"Las Piedras or bust!" cried Fred. The car was silent for most of the remainder of the trip, and it was not until they reached Las Piedras that they finally broke the silence.

"Here we are," said Fred. "Las Piedras at last!"

"We're almost there, sighed Barney. "Just a good rest and we'll be at Mt. Goldrock."

"YABBA-DABBA-DOO™!" exclaimed Fred.
