Wally asks Bobgoblin why Libby likes fairy things. Bobgoblin told Wally that Libby loves fairy things because she's a fairy.
They came across the Wonder Dragon birthday store when Norville said when next year's for Norville's birthday, he was going to have a Wonder Dragon birthday party. But, Wally told him that he already celebrated his birthday party last time with the Cake Monster. When they got to Libby's place, Libby told them that she has to cancelled her birthday party because someone had stole her fairy decorations and her fairy birthday gift.
Norville told them that they can buy the Wonder Dragon decorations from next door instead of fairy decorations. But, Bobgoblin told Norville that Libby is upset because her birthday party ends into a disaster.
Then, they saw some swamp monster prints on the floor. They learned that Stan had stole Libby's fairy birthday decorations and her fairy birthday gift. They saw Stan's swamp so far away that they must get their quickly. Wally know that today's magic word starts with the letter 'P'. He created the word 'Plane', so they can fly there very quickly. After the four get to the swamp, they saw Stan having his own birthday party with Libby's fairy birthday decorations and her fairy gift.
Wally got so worried and asked Stan why he has Libby's fairy birthday decorations and her fairy birthday gift. Stan got a grumpy answer to him because he needs the decorations and present for his own birthday party. Libby got so upset that Stan has her decorations and present.
Stan told them that he will must beat them in a party game. He told them that they must play two party games. If he won, he will give them the fairy present back. But if they all won, nobody will take the present back. First, they play Pass the Parcel. Stan turns on his radio and they started giving gifts to another person. Stan stops the music. And Bobgoblin won. Stan make fun of them because he win and they will never get the present back.
Bobgoblin is out of the game. Stan then resume the music. He stopped the music, and Libby won. Stan kicked Libby out of the next round. Round 3, he resumed the music again and left with Wally and Norville. Wally won. And Stan is laughing at him because he won and didn't get the birthday present back. Round 4, Norville is the last one. Stan resume the music and they started giving the gift to Norville to Stan. Then, Stan won and he opened up the gift which is his bunny slippers.
Stan told Wally, Norville, Libby and Bobgoblin that they will have the fairy gift back. But he couldn't give the gift back until they play another party game. If someone wins, get some Wonder Dragon balloons. Norville want the balloons because they're cool. Norville then flies to the table and gets the present back. They all ran back to the plane when Norville saw the coolest Wonder Dragon present inside the Wonder Dragon birthday store.
Bobgoblin told Norville that Libby doesn't want a Wonder Dragon present because it's not for girls, when Bobgoblin said 'Let's go back to the plane! Or the present will be get back by Stan!'. Stan gets the present again and they all went back to the swamp. Next party game is Pin the Tail on the Donkey.
