Bob and his crew set out on their adventure to Goldfields. Their plan was to mine for gold and Bob could return home very rich. To get to Fixham Harbor in time, Bob and his team had to drive for over 14 hours. Along the way, Bob and Wendy, along with their cat, Pilchard and Roley's friend, Bird, stopped for some food and for the machines to rest at a truck stop. "This is great food, Wendy!" Bob said as he finished the last bites of his hamburger.

"We still need to get to Fixham Harbor, Bob. The ferry will be waiting for us." Wendy said.

"Right, Wendy." Bob said as he stood up from his seat in the diner. Wendy followed him outside to see the machines "Okay, gang, let's go!" Bob said.

"Wait, Bob! The tire on my trailer is flat!" said Panther, who was pulling Spade on his trailer. "Okay, we'll fix it." Bob said. Scoop, Muck, and Roley were all pulling a trailer with other items the team needed, like a generator, a water pump, tools, food, and other mining supplies, where Bob found an air compressor tank with a nozzle. Lofty lifted it out of Muck's dumper bed and set it down next to Panther's trailer. Bob lowered the ramps for Spade to back off, then, in a matter of minutes, the tire was refilled and the convoy was back on its way to Fixham Harbor. By morning, Bob and the team arrived at the harbor, where their ferry awaited them.

"All aboard, next stop, Goldfields!" a man shouted from the boat. "There's our boat!" Bob said. The machines made a mad dash for the ferry, and barely made it aboard. The horn sounded as the ship set sail from Fixham Harbor and off to Goldfields. The ship began its journey, and Bob and his team were hopeful, but stormy clouds appeared on the horizon. Thunder rumbled and lighting flashed.

"Oh my! I'm scared!" whimpered Lofty.

"We'll be fine, Lofty!" comforted Scoop.

"I don't know about that, big banana!" Benny said as he looked out to see multiple waves coming in.

"Brace for impact!" Exclaimed Muck as the wave crashed against the ship. It pitched and rolled in the squall as Bob and Wendy took cover.

"Scoop, you're in charge! Wendy and I are going to the wheelhouse where it's safe!" Bob shouted over the thunder and lightning.

"Okay, Bob!" Scoop said. "Everyone, stick together!" he said as he turned to the rest of the crew. They all braved the waves, but suddenly, water spilled over onto the deck, then, screaming was heard.

"HELP!" screamed Lofty. The force of the wave had pushed him back, breaking through the railing and his back wheels were dangling over the churning sea.

"I'll save you!" Spade said as he stretched out his arm, still parked on his trailer. "Get me some chains!" Spade shouted to Benny. The small digger rushed to the aft of the ship to find some chains, and he did, picking them up with his claw and dashing over to help Spade pull Lofty back onto the deck. In the wheelhouse, Wendy exclaimed, "Lofty is in trouble! We have to help him!" Bob said.

"I can't let you! It's too dangerous!" the captain grunted as he wrestled with the ship's helm. Bob needed to help his machine, but he couldn't. Back on deck, Spade heaved and hauled with all of his might, but Lofty was too heavy.

"I've got an idea! Lofty, stretch your hook out!" Scoop said. Lofty did as he said and hooked up to the railing on the other side of the ship. "Now, Spade, pull! PULL!" he shouted. The two machines pulled with all of their might, and in no time, Lofty was back on the deck.

"That was close!" said Lofty. By now, the sun had come out, and Bob and Wendy came down on the stairs "That was quite the rescue, Scoop!" Bob said.

"Yeah, thanks!" Lofty said, gratefully.

"Anything for a friend!" Scoop said. Within a few hours, Bob and crew finally arrived at the Goldfields port, where they were ready to get to their claim on a place named Diamond Creek. There, they unloaded from the ferry, where they convoy continued on its journey. They passed through the lonely forests on gravel roads, barely wide enough for the machines to pass through until they arrived at a very mucky part of the road.
"Yippee! Mud! I love mud!" Muck cheered as she romped around in the mud, splashing dirty water on Scoop. Scoop playfully threw some back at her, then Benny got in on the fun and threw some at both of them.
"Scoop! Muck! Benny! Stop! You'll get the equipment dirty!" Bob scolded them.
"Sorry, Bob!" Muck apologized as they pressed on. Suddenly, at the back, Piper, pulling Brick, became bogged down.
"Help!" he shouted. Bob signaled the others to halt as he went to take a look. Piper was bogged down to his fenders in sticky, black mud.
"All that weight on your trailer is making you too heavy!"Bob said. He lowered the ramps for Brick to back off, then he hitched the heavy bulldozer up to Piper. Brick heaved with all of his might, his smokestack belching pitch black smoke into the air, only for him to become bogged down as well.
"I'm stuck, Bob!" Brick called out. Bob was frustrated. He then had an idea.
"Stay there, Brick, help is on the way!" Bob said as he lowered the ramps on Panther's trailer, allowing Spade to get off. The big excavator then crept and crawled his way into position, where he stretched his bucket out and flexed his grabber thumb out of the way, then he grabbed Brick's blade and pulled Brick out of the mud, who was able to rescue Piper in the process.
"Great teamwork, gang. Now let's fix the road. Can we fix it?" Bob said.
"Yes we can!" the machines enthusiastically responded. Scoop, Muck, Spade, and Axel gathered sand out of the hill, then spread it onto the ruts in the mud. Brick evened out the surface. Next, the team gathered stones from a dried up riverbed to keep the road from washing out, then Brick distributed them across the surface. Finally, Roley squished it all flat and the team was able to continue to the claim. After a few minutes of driving, they finally arrived at the claim. There, a man was waiting for them. He was the claim owner, Jerry Milgram, and a few of his machines were with him...
