It started with Mayor Goodway, Chickaletta, Dr. Turbot, and Taylor Turbot going on safari in the Dino Wilds, the turbots showed the mayor a triceratops eating its favorite plant. Mayor Goodway wants to get a group shot of them in front of the dinosaur. Dr. Turbot warned her that triceratops are scared of camera flashes, so the mayor turned off her camera flash light. But, as she lowered her phone to Chickaletta, without anyone noticing, Chickaletta accidentally turned the flash back on. Mayor Goodway took the picture, but when the flash fires, the triceratops got scared and tromp off. Everyone got out of the way, but Chickaletta started to ride on it. They help to save Chickaletta and calm down the triceratops, they began to call the PAW Patrol.
At the Dino Tower, Ryder got the call and said the team's on their way. Rex and Rubble hopped into their vehicles and so did Ryder, and off they go to save the day. Ryder was locating the triceratops on his pup-pad's GPS, and it said it's heading for Bighorn Rock, which is where the nesting grounds are for velociraptors, The triceratops could scare them off and crush the eggs by mistake. Rex knows a shortcut there as he leads the way. They went through the trees and pass the Tyrannosaurus Rex.
Meanwhile, the triceratops was still tromping around, it's heading for a velociraptor's nest. Luckily, Ryder and the pups made it in time. Rex told the momma raptor that their here to help her. The triceratops is getting closer, they need to move fast. Ryder asked Rubble to get some leaves from the palm trees, and Rex to move the raptor eggs onto Rubble's soft nest on his shovel. Rubble had finished the nest and Rex used his vehicle's dino-claw to pick up the eggs and put them into the nest. They finished it in time, even with some help from the momma raptor, the triceratops ran by without stomping on the eggs.
The triceratops was still tromping, Ryder asked Rubble to move the eggs and their momma to Dr. Turbot's for safety and Rex to continue with him to slow the triceratops. Rubble drove off the compound with the raptor following him. Ryder needs something to calm it down, and Rex came with an idea, a sicass plant. A few minutes later, Skye came by and gave the plant to them. Rex picked it up and head for the triceratops. As they got close to him, Rex was able to slow him down for Ryder to get Chickaletta off of the dinosaur. The triceratops finally stops tromping and even started to eat its snack.
As the mission was done, Mayor Goodway and the Turbots thank the PAW Patrol for saving Chickaletta, the velociraptor and her eggs, and calming down the triceratops. And Ryder said, "If you ever got a tromping triceratops to stop, just yelp for help." Mayor Goodway began to take another group shot, without the flash this time. And the short ended with the picture of the velociraptor sleeping with her eggs, Mayor Goodway, the Turbots, the PAW Patrol, and even the triceratops smiling in the background.
