Lincoln and the Grimwood students were taken on another trip by Shaggy and Scooby; but this time it was to a concert headlined by the Hex Girls! Shaggy and Scooby had met them several times and had gotten them the tickets and the girls really liked their music; Luna had gotten a ticket for herself as her band were being driven to attend the concert with their own tickets.

In the hall of the building Lincoln was talking to Sibella and Phantasma; "I love being a concerts; all the music and excuses to scream as loud as I want!" Phantasma had said excitedly with Lincoln smiling.

"Not in my top list of favourite bands but I do like the Hex Girls' music; plus the positive messages that they promote is awesome." Lincoln said with Phantasma shaking her head quite vigerously and Sibella grinned.

"They are a band I can really sink my teeth into." Sibella said and then her and Phantasma's faces fell as Luna came forward smiling at Lincoln who smiled back.

"Just here for a quick word before I join my band but have fun you all and hope this concert date goes well for you brah." Luna said with a nervous smile and wave before she left.

"A good thing that she wasn't here to hear what you said about Mick's music..." Lincoln whispered to them as Mick Swagger was performing at the concert and when they came across a poster; it turned out none of the 5 ghoul girls were a fan off his music. Luna learning that and their choice words would have ensured a confrontation happen where Luna would end up hating them which would make things worse than they already were.

"Excuse me young music fans; can I interest you in autographs or backstage passes?" offered a young hispanic man (who looked like he was in his late teens) who came forward.

"Sounds kind of you like Sibella." Phantasma whispered to Sibella who did find it odd

"Okay everyone; we are all going to our seats inside so..." Shaggy said coming over with Scooby but then they paused and stared at the man. "FLIM FLAM?" Shaggy and Scooby had screamed.

"Shaggy! Scooby! My old friends! It's been too long!" the man smiled at them warmly. "Flim Flim Flam's my name and I heard that my old pals were now school gym teachers so you must be his students?" Flim Flam greeted the trio of students surprised.

"You know him?" Lincoln asked as both Shaggy and Scooby nodded at once.

"We were out and about one summer many years ago on behalf of Vincent Van Ghoul himself. Rounding up 13 ghosts to return to a chest." explained Flim Flam as Sibella and Phantasma were in thought.

"I remember my dad telling me about this; a chest locking away 13 of the most dangerous demons to have ever walked the earth." Sibella explained as Lincoln looked scared.

"I heard as well; they had to be found after two mortals were dumb enough to be tricked into opening it up to release them." Phantasma said as Shaggy and Scooby sighed shaking their heads. "You helped catch them again? Shaggy, Scooby you both are more awesome than we thought! We should let the other girls know!" Phantasma screamed excitedly as Shaggy laughed humbly.

"Well we should all be finding our spots now. Nice running into you Flim Flam." Shaggy said as then they noticed some angry people pointing to Flim Flam while talking to some security guards.

"Well I had best skedaddle myself; nice getting to see you both again as well." Flim Flam said as he then began running away.

Yes believe it or not the late Susan Blu voiced both Sibella and Flim Flam.
