It started at Mr. Porter's Cafe, the PAW Patrol were making a tower of pizza. Chase was launching pizza dough towards Rocky, Rocky was using his grabber to toss the dough flat, Ryder was adding the sauce before Skye would the cheese, then he put the pizza in the oven, while put the ones already baked on top of one another below a wagon. Alex explained to Mayor Goodway that they need to make the world's tallest pizza tower so they could have a picture in the record book. But, what they didn't know is that Mayor Humdinger and the Kitten Catastrophe Crew were spying on the event. He wanted to win the trophy, so he came up with an idea of cheating.
A few minutes later, everyone was waiting for the judge to come and check their pizza tower. Mayor Humdinger arrived with his tower of pizza, he was sure it could win for good, but then, the PAW Patrol arrived with their pizza tower, and it was extra tall.The judge arrived in time to see the towers. Humdinger started doing some cheating again. He started to interrupt to show the judge his pizza flying. It was Cat Skye carrying it around. Everybody followed the pizza but then, Humdinger and his kittens started making the tower shorter by throwing pizzas off. And, Humdinger released Garbie to eat the pizzas, and other critters around smell the pizzas they followed the scent.
Everyone discovered Cat Skye carrying the pizza, everyone went back to Town Hall, and they saw Humdinger ruining their pizza tower. The judge came by to measure the tower, but then his ride got stuck to the pizza's wagon. And now, he started wheeling out of control. Ryder calls the pups to the Lookout for the rescue. A seagull dropped a pizza on Marshall making him blindfolded. He knocked into the other pups and said, "Who wants pizza with Pupperonii?" Everyone got geared up, and Ryder told them about the pizza tower being rolled away with the judge. He hired Skye to use her harness to lift the judge off the runaway pizza tower, Chase to use his net to stop the pizza tower before it causes any damage, and Marshall to use his water cannons to lead the critters away from the pizza tower. Everyone was ready, and off they go to save the tower of pizza.
As the PAW Patrol arrived, the judge was still going out of control. Skye started using her harness to help, and the judge was safe and sound. Marshall started using his water cannons to give the critters a drink. Ryder helped him leading to the forest. Cat Zuma was riding the pizza tower, Cats Chase and Marshall, but the tower was still going crazy, they couldn't get down. Chase used his net to stop the tower, but the kittens were flung off so high, heading towards the bridge. The pizza's cheese was strapped to the bridge, it was gonna fall at any second. Skye started using a basket to catch the kittens. The kittens jumped in the basket in time before the pizza fell and got eaten by a whale.
Back at Town Hall, the judge present the town's pizza tower the tallest ever. He took a photo of Alex holding the trophy next to the tower. Mayor Humdinger was punished once again by cleaning the Chickaletta statue.
