Lori Loud paced anxiously. Ever since Bobby had called her last night to warn her that the next specter from the Chest of Demons was coming to her college she had been a bundle of nerves. If the ghosts trashed her campus it could get her in a boatload of trouble with the dean. She looked up from her phone excitedly when she saw Vanzilla pull up at the curb and Leni, Luna Luan, and Lincoln got out. "Thanks for getting here so fast" she greeted.

"No way we'd make you face this ghost on your own dude!" Luna replied.

"Bobby just texted me, he's bringing the Chest of Demons along with Shaggy Velma and the dogs" Lori replied.

Rita Loud stuck her head out of the van. "I'll be right back kids; gotta park in the deck."

"Ok Mom, we'll be right here" Lincoln replied.

"Any sign of this mirror ghost we're supposed to be looking for?" Luan asked.

"How would she know? It would look just like her." Leni remarked.

"No Leni, the ghost isn't a mirror, it's just hiding inside one," Lincoln replied.

The Louds were interrupted by the sound of the honking horn of the Mystery Machine. Shaggy was driving, Velma in the middle, and Bobby waving out the passenger side window. As they pulled up, Scooby and Scrappy jumped out of the back and Bobby and Velma disembarked while Shaggy drove on to the parking deck. "Sorry we're late Babe!" Bobby greeted with a hug.

"It's ok, they just got here too," Lori replied.

"Well I am so ready to catch that Reflector Specter" Scrappy said with confidence, miming boxing.

"Take it easy Scrappy, first we have to find the Mirror of Marrakesh. If Weerd and Bogel have moved it into the library they must have a reason," Velma replied. "We'd better split up, someone needs to check where the deliveries come in. Lori, do you know where that is?"

"Yep, it's behind the cafeteria" she replied. Lori and Bobby went to go check it out and Velma insisted they take Scooby and Scrappy with them. The others went on into the library to begin their search there.


There were no trucks in the loading bay but a bunch of different packing crates were staged to be picked up. "They could be hiding in any of these Uncle Scooby! We better get started!" Scrappy said as he grabbed a crowbar.

"No no no Scrappy, be careful if you break anything we may have to replace it" Lori replied frantically. "And besides we're looking for a mirror, if you break that isn't that seven years bad luck?"

"Don't worry Lori, I won't break anything!" Scrappy said as he began pulling open a crate. The side fell off and thousands of golf balls poured out in an avalanche. Scooby began slipping continuously under the balls and slid across the lot loading bay into a package slot in the wall. "That's my Uncle Scooby, leaving no stone unturned."

Scooby lay in a daze for a moment, the front half of his body was no in a hallway inside the university cafeteria. He was still recovering from dizziness as Weerd and Bogel turned the corner carrying the large wrapped package that contained the mirror. "Careful Bogel, if we drop this we are gonna be in so much trouble!" Weerd snapped but he cut himself short when he heard an 'ow'. The two ghosts turned around as Scooby Doo snapped back to his senses after having his paw stepped on, all three of them freaked out momentarily. Then the ghosts ran as fast as they could without dropping the mirror.

"Rori, Robby, Scrappy, Relp! Rhosts!" Scooby cried, and the others saw his tail stick straight up.

"Ghosts?" Bobby said, and grabbed Scooby's hind legs to try and pull him out.

Scrappy meanwhile had a different idea, he grabbed a jackhammer. "Hold onto them Uncle Scooby we're coming!" Lori watched in horror as Scrappy hopped on Scooby's back and began trying to break a hole in the wall. Finally Bobby yanked Scooby free and he and Scrappy fell backward on top of him. The jackhammer went flying and went down a storm drain.

Lori cringed as she examined the crack Scrappy had left in the now damaged wall. But it had not collapsed, thankfully. "Scrappy, next time just use the door!" she pointed at the door right next to the package slot.

"Hey, I'm just a puppy and I'm entitled to make a mistake or two" Scrappy replied as they went inside. Weerd and Bogel were gone and so was their package. "You must have scared them away Uncle Scooby."


Meanwhile, Lincoln, Leni, Luna and Luan were searching the library stacks stealthily. Lincoln had his official Arrrgh ghost containment device. Shaggy had informed him they would most likely need to suck the Reflector Specter out of the mirror before depositing it back into the Chest of Demons so he came prepared. "Careful guys, they could be anywhere," he warned.

"Don't worry Linc, I'm not gonna let them sneak up on us" Luan replied. She walked backwards in perfect step with Luna with all angles of vision covered between them.

"They're not in the bathroom," Leni reported. Her siblings looked at her, confused by her choice of where to search. "What? Why wouldn't a mirror ghost want to be somewhere with more mirrors?"

Shaggy entered carrying the Chest of Demons and Rita right behind him. "Kids, any sign of your ghost?" she asked.

"Not yet, but they aren't over-due yet. Hahaha get it?" Luan replied.

Velma was studying the computer where she had accessed the library's catalog. "There's no way Weerd and Bogel brought the Reflector Specter here just to scare Lori. There's something in this library they want and we need to find it first. Shaggy, do you have Vincent Van Ghoul's mirror escaping medallion?"

"Zoinks!" Shaggy said. Cause everyone to look at him like 'seriously'. "Cool it dudes, I've got it here but I just realized we left Mr. Van Ghoul's crystal ball at the Casagrande's." Shaggy pulled the medallion out of his shirt.

"And we left our ball at home too. Lucy wanted to try some possible spells to try and release Mr. Van Ghoul from inside" Lincoln said distressed.

"Well what was he gonna do? Dude's stuck in a crystal ball" Luna replied. She then heard something moving behind the bookcase. "Wait, you guys hear that?" Following the sound she jumped as the back door opened. Lori, Bobby and the dogs rushed in.

"Oops, sorry Luna, hope we didn't scare you," Lori said. Luna had jumped into Luan's arms like Scooby usually did in Shaggy's.

"Uncle Scooby almost had them, but that slot was not built to handle his muscles" Scrappy bragged. Scooby sucked in his tummy to give the impression that he was indeed too muscular and not too fat.

Velma meanwhile finally stuck her head up from the computer. "Jinkies I don't know why I didn't see this earlier. There is a collection of restricted books, that are super rare and unavailable to the general student base, they are kept in a secret, temperature-controlled vault is under the library" she exclaimed excitedly.

"I remember there were rumors of a secret second entrance on the 14th hole of campus's main golf course," Lori said.

"Great Lori you go try to find it" Velma replied.

Lori thought for a moment and then stopped, "wait, I don't want to go alone, there are literally three ghosts running around!"

"Don't worry babe, I won't let them get near you!" Bobby said. Lori smiled at her boyfriend, imagining him as a brave knight.

"Well while you guys do that, I'm gonna outfit this library as one big Scrappy trap, in case Weerd and Bogel try and make a play for the Chest of Demons!" Scrappy declared. Rita chuckled. "Don't worry Mrs. Loud, a Scooby Scout is always prepared!"

"Wait a minute guys, something doesn't make sense, Velma you said the vault was under the library, but it doesn't have a basement" Lincoln replied.

Velma pondered for a moment, "it must have a hidden entrance."

"Well, if it's hiding, it could take us all night to find it" Leni said, but as she leaned on the wall there was a clicking sound. A bookshelf slid out to reveal a hidden elevator. "Oh, that was fast!"

"Great job Leni, let's go!" Lincoln exclaimed as he, Luna and Luan got inside, and Leni followed. "There's room for one more." Scooby hoped someone else would volunteer but Scrappy knocked over a stack of books as he was setting up his trap, startling him. He jumped into the elevator. "Thanks Scooby!"

"Wait Scoob, don't forget the amulet!" Shaggy said, tossing it inside as the door shut.


At this time in the basement Weerd and Bogel were unwrapping the Mirror of Marrakesh so the Reflector Specter could see. The blue demonic ghost appeared in the mirror. "You did well sneaking us down here. Now only one door stands between us and the magic tome that may prove key to Maldor's return." He laughed.

"Alright, we'll you're supposed to be the one who can get in this door. Apparently, Van Ghoul himself put up a no-phasing-through spell, so make with," Weerd stopped speaking as they heard the elevator door approach.

"Hide you fools, someone approaches" the Reflector Specter declared before vanishing into his mirror. Weerd and Bogel ducked behind the crate.

Scooby Doo and the Louds exited the elevator. "Looks like we got here first," said Lincoln.

"But how are we supposed to get into that vault?" Luan asked.

"Yeah dude, we better hope Lori has better luck with the second entrance" Luna added.

Looking around Scooby spotted the Mirror of Marrakesh propped against the wall, He pointed, "rirror!"

"Mirror? What? Do I have something on my face? Don't look at me!" Leni exclaimed. She spotted the mirror and darted over to look at herself in it.

"Leni wait!" Lincoln exclaimed. But it was too late, the Reflector Specter appeared in the mirror.

"Surprise meddling kids!" he exclaimed and began sucking Leni into the mirror. The kids scrambled to pull her free. Scooby tried to pass off the amulet to her but the Reflector Specter spotted him. "Well, well, well, I was hoping I'd catch you, Scooby Doo!" Scooby wailed in horror.

"He's sucking us in," Luan cried. Their grips began slipping. Leni vanished into the mirror first as the others watched in horror. Luna's hand was still holding onto Leni's; they formed a human chain with Lincoln in the middle and Luan using one hand to brace to the bar in the elevator. Scooby claws began to lose grip and he was next to fall through the mirror. Luna watched in horror and her grip slipped. Lincoln and Luan were thrown back into the elevator as their third oldest sister disappeared after the others into the mirror world.

The elevator door began closing. "Don't go foolish mortals, things are just getting started!" The Reflector Specter shouted.

Weerd and Bogel jumped for joy! "You got three of them! Including the pesky dog!" Weerd cried.

"Now is not the time for celebration! You two, get over to the golf course. They said the others are searching for a second entrance. They must not be allowed to get in before me!"

"B-but what about you?" Bogel replied.

"They wouldn't dare try to catch me so long as I hold their friends. Haha. Just leave me pointed at the vault door," he instructed.


Upstairs and unbeknownst to what was happening Scrappy had built an elaborate ghost trap as Rita Loud watched. Shaggy had gone to the golf course with Lori and Bobby; while Velma was still researching. Scrappy was in the middle of explaining his sprawling creation, when Rita was drawn to a crying sound. She rushed to the elevator where Luan was sitting on the floor bawling with her arm around Lincoln who was teary eyed and hyperventilating. The Loud mother bent and hugged her children.

"Mom, they're trapped, the mirror ghost sucked them in" Luan managed to say through her wailing. "It's all our fault!"

That broke her mother's heart, "Sweetie don't say that," Rita replied.

"But Mom, we opened the chest, the ghosts got out because of us. Luna, Leni and Scooby were just trying to help us and they got sucked into another dimension." Lincoln added, as he put his forehead to his Mom's shoulder.

"Lincoln, Luan, stop. I will not let you beat yourselves up. You have such big hearts. This is not your fault! We will fix this together, that's what families do!" Rita let her own tears shed as she held her children tight. She worried about Leni and Luna lost in another dimension, and that made her want to hold onto Luan and Lincoln even tighter.

Velma upon hearing Scooby had been sucked in along with the two Louds, immediately looked to Scrappy who was unusually anxious. She scooped up the puppy into a hug. "Don't worry Scrappy, Scooby will be ok. He's beaten this ghost before, and he can do it again." And she meant every word of it.


Meanwhile at the Fourteenth hole. Lori was looking at the hole while Shaggy examined the green and Bobby searched the rough. "Well I've gotten a hole in one here before, so that's obviously not the key to the entrance" Lori deduced.

"Nothing here," Bobby hollered, "yikes, except for an anthill!" He stumbled, shaking off his foot.

Shaggy, an experienced caddy and mini-golfer, noted something off about the green. "Like Lori, how often do you see folk end up in that sand trap?" He pointed to the one built into an incline to the right of the hole.

"Literally never," Lori replied after going over it in her head.

"Well the green is warped so that it will never roll into that trap. Like why would they design it that way?" Shaggy explained.

"Except maybe so no one accidentally finds their secret door" Bobby chipped in.

"Like I wish Scooby had come, looks like we're gonna have to do some digging" Shaggy lamented. But before they could start a flurry of golfballs rained down on them. They looked over and saw Weerd and Bogel riding on a lawnmower. As the ghosts drove they launched the balls like a hailstorm.

"That is literally so bad! They're gonna break that thing and scratch all those balls!" Lori yelled angrily.

"Babe, I don't think they care!" Bobby said. He and Shaggy grabbed the wedge and the iron out of the golf bag and started digging into the sandtrap. They could hide inside if they found a secret entrance.

"Guys those are brand new clubs!" Lori cried.

"Well your putter wasn't made for digging!" Shaggy replied. They built up a cloud of sand that blew in the wind right into the eyes of Weerd and Bogel. The ghosts panicked and crashed into the lake.

Disgruntled, and dripping wet, Bogel complained, "do they not realize it's hazardous to keep water on a golf course." Weerd, who was well aware of golf course water hazards, smacked him.

"Score!" Bobby exclaimed as the golf clubs struck a hatch door buried in the trap.

"Get it open, hopefully everyone else is already down there!" Lori replied.


Technically Leni, Luna and Scooby were down there but trapped inside of the Mirror of Marrakesh with the Reflector Specter. Leni was on an upside down platform looking at her sister who was standing on one that was spinning. The world was filled with colors. They were safe for the moment as the Reflector Spector was attempting to move through reflective surfaces on the lock.

"O-M-Gosh Luna, you're upside down!" Leni exclaimed.

"No Leni, you're walking on the ceiling. We're inside the mirror" Luna replied.

"Well I can't see myself, we've gotta get out of here so I can see whatever was on my face!" When Leni said that, Luna facepalmed.

"Relp!" they heard Scooby calling. They had forgotten for a moment that the great dane had been sucked in alongside them. They called out his name but his yelps echoed. Finally, they spotted Scooby who was running in zero gravity chasing the amulet which was floating away from him.

"Hang on, Scooby we're coming!" Luna cried jumping and swimming from spinning platform to spinning platform. Leni was still trying to get herself up right by stepping over the edge of the platform. Luna reached the Scooby who was pointing at the amulet. "Don't worry Scooby dude, we'll get the amulet!"

Suddenly the Reflector Spector appeared in the air and grabbed them both. "Oh no you don't, you're not getting away. You will never get that amulet!"

"You mean this amulet?" Leni cried, having caught it as it floated by.

"Leni use it!" Luna said as she squirmed in the demon's grip.

"No you give it to me or else" the ghost was saying before Leni interrupted.

"Do you mind! I'm trying to read the instructions" she read what was on the back of the amulet. "Mirror mirror, magic portal, open up for this poor mortal. How am I supposed to do that?" But before any of them could do anything, the mirror world started spinning. The three of them were ejected from the mirror crashing into the vault door as the mirror was facing it. At the same time, Shaggy was opening the door from the other side.

"Like about a minute too early Scoob!" he replied with a laugh. Scooby grumbled, the door hurt when they slammed into it.

"Look at all these books, how are we gonna find the right one?" Lori said from inside the air conditioned room.

The Reflector Specter appeared in the mirror and emerged like a 3-D movie monster. "You will not live long enough to find it, mortals!"

"Zoinks, I forgot how ugly this ghost was" exclaimed Shaggy.

As they began pelting the demon with books, Weerd and Bogel slid down the ladder unnoticed. "Wow! this party is in full swing!" Bogel commented.

"Never mind them Bogel, look there" Weerd pointed to a book covered in ancient runes. "That's the one Maldor wants." Bogel was snatching the book when Weerd was smacked by a stray book. "Hey watch it" Weerd replied and hurled it back. But Leni ducked and the book smashed into the Mirror of Marrakesh creating a spiderweb styled pattern. The two bumbling ghosts were speechless and embarrassed.

"Now look what you've done you fools" the Reflector Spector shrieked. He was no longer able to retreat into the mirror but remained projecting out of it. "You will all pay!" But before the Reflector Spector could speak a vacuuming sound started humming. He turned to see the elevator had opened with Luan, Scrappy, Velma, Rita and Lincoln who was using his Arrrgh! ghost vacuum to try and suck the demon towards them. "That won't work twice, meddling mortals!" the ghost snapped.

"Maybe so, but this will!" Scrappy said. "Hocus Pocus, spirit rest, return oh return to the Demon chest!"

As Scrappy spoke the magic words, Luan produced the Chest of Demons and the combined suction pulled the Reflector Spector into the chest which she then snapped clothes.

"Uh oh, time to go!" Weerd said as the two ghosts rushed up the ladder. Bobby just missed grabbing them. But as he looked up to the hatch he heard them mumbling to each other. "We should have offered them 200 instead of 20 dollars like we did the others at that funhouse!"

Scrappy grabbed his Uncle Scooby, "I knew you'd be ok, I just knew it!"

Lincoln, Luan and Rita grabbed Leni and Luna into a big group hug. "We were so scared, we thought we had lost you!" Lincoln said, his voice muffled in the hug.

"It's okay, bro, we're here" Luna said, tearing up.

Lori deduced what must have happened and smiled, she was relieved Leni Luna and Scooby were safe. She turned as Bobby stood next to her. "Those two funny ghosts got away with a book. But did you hear what they said?" Lori shook her head no. "They were there talking on the loudspeaker the day we opened the chest, and they deliberately offered us less money so we would pick the chest as our prize."

The rest of the group was shocked. "That means they zeroed you out. They picked you to open the chest, out of all the people at that fair. It wasn't random!" Velma exclaimed.

"But why them?" Rita asked, her hands on Lincoln and Luan's shoulders, the siblings still side hugging Luna and Leni respectfully.

"Like I guess that's another mystery for the list." Shaggy lamented.

Bobby, Lori, Leni, Shaggy and Scooby went back up in the elevator first, and the rest crammed in for the second trip. But when the door opened, they found the library a complete mess, the result of Scrappy's setup being activated. The first party was caught up in ropes dangling from the ceiling. "Gee Uncle Scooby, I know we didn't need my Scrappy trap to catch the ghosts, but it was nice of y'all to test it!" Scrappy declared. The rest of the kids as well as Velma and Rita laughed!
