Mr. Porter was about to deliver fizzy pickles to the citizens of Adventure Bay. He and Alex did a taste test, and the fizz makes them ticklish in their mouths; they were extra fizzy. They loaded the pickle jars into the delivery van. Mr. Porter had to be careful not to make the jars all shaky because if the jars shake, the fizz inside can make it pop like soda cans. Once he was all ready, he drove off to deliver the fizzy pickles around town.
Mr. Porter was driving on a bumpy road full of potholes and rocks. And, as the van was bouncing up and down, it made the jars all shaky. He gave one jar to the PAW Patrol, who were working on fixing the road, and Rubble was excited about it. After Mr. Porter continue his delivery making, the PAW Patrol were finished fixing the road and started to have fizzy pickles for a snack. Rubble brought over the jar and Ryder sees that the pickles are really fizzy.
Mr. Porter gave pickles to Cap'n Turbot and Wally, before they sail out to the bay. Once they got out to deep water, the jar was moving. And then, it exploded pickles out. The pickles were zooming around like missals, they made Cap'n Turbot fell overboard, knocked off the boat's ladder, and turned on the Flounder's engine, making sail away on its own. Cap'n Turbot was stuck swimming in the bay, luckily his phone was waterproof, so called the PAW Patrol for help.
The PAW Patrol made it back to the Lookout, when Ryder Cap'n Turbot's call for help. He summons the pups to the Lookout. Marshall was sitting on the pickle jar that Rubble had dropped, and it bursts off the ground let Marshall zoomed to the elevator like a rocket. The pups got geared up and Ryder explained to them that Cap'n Turbot fell overboard by the fizzy pickles. It's up to the team to rescue him, get him back onboard, and stop the Flounder. Ryder hired Zuma to his hovercraft buoy to rescue the captain from the ocean, and Rocky to ride on his tugboat, fish the ladder out of the water, and use his tools to fix it so the captain can climb back onboard once Ryder slows down the boat. Once they were ready, they deployed in their vehicles, and off they go to save the day.
While Ryder and Rocky were catching up to the Flounder, Zuma used his buoy to help Cap'n Turbot. Rocky fished the ladder with his tugboat's crane. Ryder reached the Flounder, sets his ATV on auto-pilot, climbed aboard, and stopped the boat. Then, Rocky reattached the ladder for Cap'n Turbot to climb up on. Ryder feared that the fizzy pickles could cause more trouble around Adventure Bay, they need to stop Mr. Porter before it happens.
At City Hall, Mr. Porter gave Mayor Goodway and Chickaletta a pickle jar, then he drove off to Jake's mountain. Goodway was excited to try some fizzy pickles, but then, the pickles popped out like a bomb. Pickles were bouncing and zooming everywhere, one was about to hit Mayor Goodway, but luckily, Rocky showed up on time and caught the pickle with his grabber. Mayor Goodway told Ryder that Mr. Porter was heading for Jake's mountain, he and Rocky started going, while Zuma stays behind to help clean up the mess.
At Jake's cabin, Mr. Porter gave Jake and Everest their pickle jar and drove off again. Jake and Everest saw the jar about to burst, they took cover inside their cabin. Pickles popped everywhere, one started a rock slide, and boulders blocked the front door, Jake couldn't get out. He started calling the PAW Patrol for help. Ryder called Rubble over for backup. Once they've arrived, Rubble and Everest started driving their vehicles to push the boulder out of the way. Jake was free, but the PAW Patrol still had to stop Mr. Porter from making more deliveries, so Ryder called Skye look him in the air.
Skye spotted Mr. Porter driving down the mountain. The pickle jars all popped, making the van speeding out off control and falling down a cliff. Once the PAW Patrol arrived, Ryder called Chase for help. Chase arrived and hooked his winch on Rocky's pup-pack, so Rocky could climb down to the van. Skye airlifted Mr. Porter up, and Rocky had found the last pickle jar. They needed a little fizzy power to get the back up easily. Rocky shook the jar and placed it under the van, before he swiftly climbed back up. The jar bursts the pickles out, letting the van fly back up the road.
After the rescue was over, the pups were enjoying the fizzy pickles. Mr. Porter apologizes to Ryder for the mess he's cause, and promised him to make the pickles less fizzy next time. Then, the episode ends with the pups trying to make the perfect pickle pun, and Rocky did it for them: "Cause Mr. Porter packs a pupping pickle."
