There is a young 20-year-old dark wizard named Damon Baraka, who is a younger half-brother of The Goblin Queen and the Light Queen. He takes his late half-sister's goblins as his servants, the goblins accepted Damon as their new leader.
"Your majesty." said the servant. "Yes?" said Damon. "I have some news for you: Oscar escapes from prison and Nikki has turned into the monster." said The late Goblin Queen's servant. "Send the guards to find Nikki and I'd be sure that she will be my new pet," said Oscar. "Yes, your majesty." said the servant.
The servant leaves to tell the guards to find Nikki. "Now, if I have Nikki as my pet. I will rule the world and destroy the Light World, nothing's gonna stop me and my royalty," said Damon.
Back to Ben and the others, they find the portal to the Light World where Nikki went. They went into the portal and enters the Light World.
"There she is!" said Franny as she sees Nikki running. "Let's follow her," said Ben.
Ben and his team follow Nikki.
As they were chasing after Nikki, Nikki went to the forest, and the team stopped running.
"We've lost her," said Franny. "Don't worry, we'll tell the Light Queen about this," said Ben. "OK, that will be fine," said Franny, taking a deep breath to prevent herself from panicking.
Ben and the others teleported to the mysterious forest of the Light World, they find Nikki's footprints.
"There's footprints, we better look around," said Ben.
The group split up to find Nikki, they must look out for dangerous obstacles. Ben goes to the first path of the 5 pathways, with Blue Eyes while the others go to separate paths.
"I don't see Nikki around, where could she be?" said Franny. "I don't know, but I'm pretty sure there are footprints around," said Red Eyes. "I'm sure about that, too," said Franny. "Nikki is my oldest sister and we have to find her to get her back to normal as possible," said Franny. "I'm pretty sure the Lightside got a cure for Nikki," said Red Eyes.
Purple Eyes, Lunick, Solana, and Summer found footprints of Nikki in the middle path of the forest. "We found footprints!" said Purple Eyes.
"Good searching, Purple Eyes!" said Kellyn.
"We'll be right back to you at any moment!" said Ben.
Ben discovers the mysterious, glowing creepy mushrooms next to one of the trees. "What are those things?" asked Ben, confused. As Ben tries to touch the mushrooms, Blue Eyes see him touching them. "Ben, I don't think you should touch them?" said Blue Eyes. "Why?" asked Ben. "Because they are poisonous," said Blue Eyes, aware that the glowing mushrooms from the Darkside are poisonous.
Ben begins to feel lightheaded and poisoned before he fainted, due to the exposure to the Darkside mushrooms. "Ben!" shouted Blue Eyes. "What happened?" said Purple Eyes as he and the others heard and come by to see what was going on. "It's Ben, he's been poisoned," said Blue Eyes. "By what?" said Summer. "Glowing, teal mushrooms." Said Blue Eyes.
"Ben, oh my gosh!" said Red Eyes as he runs to Ben's aid. "Ben, can you answer us? Say something?" said Lunick. "Guys... I... (coughs)." moaned Ben, in a poisoned tone. "Come on, guys, we gotta take him to the Light World kingdom.
As the team and Franny takes Ben to the Light World, Oscar watches them. When they got back to the Light World kingdom, everyone becomes concerned. "What happened?" said Claudina. "It's Ben, he touched the glowing mushrooms and he is being poisoned by them," said Kellyn. "Guards, take Ben to the medical bedroom." said The Light Queen. "Yes, my queen." said one of the guards.
The guards take Ben to the medical room, and the team becomes worried. Claudina comforts a worried Kellyn with a hug.
