The Celestian Alliance, The Freaky 6 and Mr. Jinn were returning to Monster High from Camp Everfree. As they were going near Bergen City, the bus blew a flat tire. Mr. Jinn needed to a mechanic fast, because if Abberan tried to help, it'll just get eaten, "Explore all you want," Mr. Jinn said, "But don't wander off and that goes for logan."

They were exploring when Ethan stopped, "Do you hear that?" he asked.

"It's coming from over there," Applejack said.

They found a hole which was too small for them to fit. Nathalia and Logan got out their shrinking potions and they turned small. Inside the hole were Happy Trolls, "Rochelle told me that Happy Trolls live in harmony in the Happy Troll Tree," Logan explained, "but one day a Bergen came and ate one and felt happy. Every year the Bergens eat one to feel happy. Around the time where Prince Gristle Jr was about to eat his first Happy Troll, only to find out that they escape. Everyone made it out and lived peacefully since then."

"Good story Logan!" Pinkie replied.

"Merci Pinkie Pie," Logan said.

"And a good PARTY!" Pinkie shouted.

Pinkie, Zach, Glowworm, and Logan rushed down and started to party up with Princess Poppy, who was a pink troll with flowers in her hair. Rarity and Janel complimented her dress.

As they were doing the conga, Stitch noticed a black haired troll looking grumpy. "What's up with him?"

"That's Branch." DJ said,"He's not a fond of singing and dancing."

Branch got cautious because they might expose them to the Bergens. Only Poppy giggled, which made Branch blush, only for him to walk off in anger. Then a local yoga instructor, "Creek" came down and thought he would show some Yoga. Warren wasn't interested, but Creek insisted.

While they were breaking a bergen piñata, Warren started to calm down. Then Creek gave him a Himalayan Monkey Pinch and realigned his neck. Warren started to mellow down and partied.

"Are you okay Warren?" Rainbow Dash asked with a cautious look.

"Nothing better Rainbow Dash." Warren calmly answered.

Suddenly, Azelf saw Nathalia standing there, "You'll get exposed by the former chef of Bergentown and 7 trolls will be captured." Nathalia predicted, "You'll gain help from 2 trolls and you'll go to the city to save them before they get eaten."

As Poppy placed up a fireworks display, a banished Bergen chef saw it and followed the fireworks to the Happy Trolls hideout, only for a few of them to get captured. "That's Chef Baranski," Abberan explained, "She was once a chef at Monster High until 2 years ago where she got fired for serving."

"How did you know that?" Ethan asked.

"I read an old article about her in the library," Abberan answered.

"He's running the party!" Pinkie shouted, "And! I! Hate! Ruined! Parties!"

Poppy knew she had to save them, but she needed an outdoor survival expert. She found Branch's hideout by the mousetraps and went down.

In the home. Mr. Jinn came trough in Happy Troll size.

"You love Poppy don't you?" Qui Gonn asked.

"Yeah!" Branch answered, "She loves me for being me and I kept all her invitations since then."

"What are you doing here?" Twilight asked.

"I got to the nearest repair shop," Mr. Jinn explained, "Only for them to kick me out for no reason."

"We need Branch's help." Will explained, "Some of the trolls have been captured."

"We must proceed," Lilo said.

They headed off to Bergen Town while everyone hid in Branch's hideout.

Note: Chef Baranski is named after Christine Baranski, who played the chef in the movie.
