It started at the Dino Tower in the the Dino Wilds, Ryder was upgrading Zuma's hovercraft fans by adding more speeds. As he was done, Zuma began to test it out, and it worked. Skye was about to check on them when the wind from the fans lifted her up into the air, and she enjoyed it.
Meanwhile, Rex was visiting a family of Velociraptors, two parents with three babies, Roary, Rosie, and Rhonda. Then all of the sudden, a Tyrannosaurus Rex appeared for attack. The baby raptors ran away in fear, while the parents were trying scare the T-Rex away. As they were chasing out of their sight, Rex noticed that the babies were gone. He started to call the PAW Patrol, and Ryder told him that they're on their way. He and Zuma hopped into the Dino Patroller with Zuma's hovercraft loaded. And off they go to help Rex.
Rex was still looking for the baby raptors, and then, he found Roary. The Dino Patroller arrived, and Ryder and Zuma got out to help. Zuma can help Rex look for the last two baby raptors, while Ryder and Robo-Dog look for the parents and meet back at the Dino Tower.
Zuma and Rex had found the last two baby raptors and brought them to the Dino Tower. Roary entered the tower and accidentally lock Zuma and Rex outside. Rex gave Zuma a lift onto the roof with his claw, and as Zuma made it, Roary caused the tower to go higher, then, lower, which caused Zuma to fall off, but luckily, Rex caught him with his claw. Roary unlocked the door, letting Rosie and Rhonda to enter. The tower was locked with Zuma and Rex outside again.
The baby raptors were causing so much trouble. Roary cause the Dino Tower to go up and down several times, and Rhonda and Rosie were about to fall off. Luckily, Zuma had an upgrade. He used his fans to catch the two sisters, but Roary was still up there. Zuma gave Rex a boost with his fans get up to the high floor of the tower. As he made it, Rex turned off the controls, and brought Roary back down.
The Dino Patroller came back the raptor parents, and the family was finally reunited. Rex thanked Ryder and Zuma for their help, and Ryder said, "If you ever need a raptor round-up, just roar for help."
