A month after the fight at Monster High, the Mystery Gang had arrived back home in Crystal Cove.
"I can't believe we got a signal from here," said Velma as the gang got out of the van in a parking lot.
"Vincent said it was a large one too so be ready for anything," said Daphne.
"V, is that you?" came a voice from behind them.
"Marcie!" said Velma while turning around to see the other girl standing there.
"Why didn't you tell me you were coming home?" asked Marcie as the two hugged.
"It was kind of a last minute thing and will take some time to explain actually," said Velma after pulling out of the hug with a nervous expression.
"Well, there's a lot of catching up for you two so we'll go home for now and try to track that thing down," said Daphne.
"Just give us a call when you're done so we can come back and pick you up," she said.
"Alright, see you all later," said Velma.
"Have fun," said Sibella before she and the others climbed back into the van and drove off.
"Who was that?" asked Marcie.
"That's also kind of a long story, how about I tell you over some lunch?" asked Velma.
"Sounds good," said Marcie while taking her hand in her own and smiling at the other glasses wearing girl. Meanwhile, the four Dark Lords were watching through a crystal ball from their little pocket dimension.
"They actually fale into our trap, talk about fools," said one of the male lords.
"Easy Sarth, we can't act yet," said the female lord.
"Clareitice is right, they need to be further into the trap and let their guard down first before we can even think of attacking them," said another lord.
"Fine, I'll wait for now Traxer," said Sarth.
"But when the time comes that whole town will die with those kids and their dog," he said.
