"Pups Save a Playful Dragon" is the first segment of the 3rd episode in Season 4 of PAW Patrol.
Rubble and Alex fall asleep while reading a storybook about Buddy the hiccupping dragon. They can't believe their eyes when Buddy jumps right out of the story and plays a game of hide-and-seek throughout Adventure Bay.
It started with Rubble and Alex Porter at the beach, reading a book of a boy named Maximus and a his dragon named Buddy. It said Buddy loves to play hide-n-seek, he had some hiccups, causing him to breathe fireballs and burn things. After they'd finished reading, they went to sleep and began to have a dream. In the dream, they heard a growling sound. And, not just that, they'd discovered Buddy the dragon missing from the book. Buddy is out of the book and appeared in real life in Adventure Bay. And, he still had the hiccups, he accidentally burned everything around town and scared everyone. Rubble and Alex decided to call Ryder about the problem. And, as Ryder got their call, he summons the pups to the Lookout. Marshall tripped a bucket, rolled towards the elevator, and bumped into the other pups. Then, Alex came by and came bumping after.
As everyone was geared up, Ryder told everyone about Buddy needing to get back to the book. He hired Marshall to put the fires that Buddy accidentally started, and Rubble to put the lemonade cup back up since Mr. Porter called about Buddy knocking it down. Then, Ryder hired Alex help out since he knows Buddy well. He even gave Alex his own pup-tag and jetpack. After everyone was ready, Ryder hopped onto his ATV and the pups hopped onto their vehicles, while Alex flew off with his jetpack on. And, off they go to save the playful dragon.
As the PAW Patrol and Alex made it to the lemonade stand, Mr. Porter was surprised to see his grandson flying. Rubble used his crane to lift the cup back onto the roof. Alex spotted Buddy flying towards the train tunnel. They believed he was trying to hide in there, so they began to follow him. As they arrived at the tracks, Buddy was riding on top of an approaching train. The train engineer saw the dragon, so he'd stop the train. Alex was trying talk to Buddy, but he flew away again. The PAW Patrol followed him to Farmer Yumi's, where he'd hiccuped on bales of hay. Marshall cooled them down, then Buddy hiccuped on a pile of corn, turned it into popcorn, and flew away again.
They followed Buddy into a cave, where the bats flew away from him. Buddy's hiccups are getting worse, they caused a small rock slide to block the cave. While, Rubble quickly used his rig to move the rocks out of way, Ryder figured Buddy was only trying to seek instead of hiding. He asked Alex to show where Max really is once Rubble reopens the cave that show him the book. But, Alex left the book at the beach, so used his jetpack to go and grab it. As he got the book and returned to the cave, he showed Buddy that Max is in the book the whole time. Buddy finally sees they're telling the truth, he lick Alex and Rubble to say "thank you," and returned into the book.
After the rescue was over, Rubble and Alex woke up. And, Rubble has gotten the case of the hiccups. They were both talking about the dream they had and checked to see if Buddy is still in the book, and he is. They knew it was only a dream, until they saw Buddy winked at them, and their umbrella burned, believing it could possibly be real.
