The PAW Patrol must take care of some colossal crops after fertilizer causes them to grow to enormous proportions.
At Mr. Porter's restaurant, the PAW Patrol are helping Mr. Porter with creating the biggest pizza he's ever made, making sure to have plenty of ingredients for the job.
Meanwhile, at Farmer Yumi's, Marshall is helping Yumi and Alex Porter with growing her flowers using something called "Zippy Grow" with specific instructions to only use one drop, but once again, Alex's attempts to help by overloading Marshall's water cannons with the Zippy Grow results in the vegetables growing humongous and getting Yumi, Alex, and Bettina trapped and in need of rescuing, so Yumi calls Ryder. Once he gets Yumi's call for help, Ryder summons the pups. As Marshall rolls towards the Lookout on an overgrown Brussels Sprout, he crashes into the other pups, who comment on how Marshall's supposed to eat them, not wear them, leaving them all with a laugh before heading topside.
Once topside, Ryder assigns Marshall and Rubble to help with rescuing Bettina and Yumi from the overgrown vegetables, and the team deploys for duty.
Once they reach Yumi's, Rubber gets to work lifting the squash off of the corn pen so Yumi can get out via Marshall's ladder. Afterwards, Rubble works the broccoli to help Bettina down, who is a little dizzy, but Yumi helps her recover with some corn, but Bettina backs up into the tomatoes, causing three of them to break loose from their stems and begin bouncing away, forcing Ryder and his pups to go after them, protecting Farmer Al from them, and then summoning Zuma to assist with controlling them until they get into town, where Ryder assigns Chase to use his net to dice the tomatoes safely into tomato sauce to help out Mr. Porter's giant pizza, while having Rocky help with setting things up to catch the tomato sauce as well.
With everything safe, Ryder has one more job for Marshall: Adding the last of the tomato sauce to the pizza. Mr. Porter, Yumi, and Al, all owe the PAW Patrol their thanks, and as Rubble tastes the sauce and voices his positive thoughts on it, it leaves everyone with a good laugh before they finish the pizza using Yumi's giant vegetables.
