"Alright, gang! Let's split up into teams and search the school grounds!" Fred said. "Daphne, Draculaura and I will be the first team. Velma, you're with Frankie. Shaggy and Scooby, you go with Mr. Where."

"What?!" Shaggy yelped. "Like, no way, man!"

"Why not? Who better to help you around the school than a teacher?" Fred pointed out.

"He has a point, gentlemen." said Mr. Where. "I'd be more than happy to assist you."

Shaggy gulped. "Uh, no offense, Mr. Where. B-But we have a severe allergy to monsters!"

"Oh, come on, you big scaredy bats!" Draculaura said. "Mr. Where is one of the nicest teachers at Monster High!"

"Yeah, guys. Don't be so judgmental for once." Daphne said.

"She's right." Mr. Where put a gloved hand on Scooby and Shaggy's shoulders. "I'm sure to be a valuable asset in apprehending the thief."

"Maybe a Scooby snack or two will change your minds." Velma said.

Shaggy and Scooby perked up. "Okay, we're listening!"

"Wait a minute, the Scooby snacks are back at the Mystery Machine!" Fred said.

"Then we're not listening anymore!" Shaggy said.

"Hey, you guys!"

Everyone looked over and saw three teens covered in brown fur and had fangs and claws! And they were shoveling some sort of food in colorful looking boxes into their maws.

It was Clawd Wolf and his sisters, Clawdeen and Howleen.

"Werewolves!" Scooby screamed.

"And they've got the Scooby snacks!" Shaggy screamed even louder.

"Clawd!" Draculaura chirped.

"Hey, Draculaura." Clawd said with a mouthful of treats. "You have got to try these treats!"

"Where did you guys get those?" Frankie asked.

Clawdeen thumbed over her shoulder. "We found them in this broken down van outside the school." she said, still eating.

"These things are drop dead delicious!" Howleen mumbled with her mouth full.

"NOOOO!" Shaggy fell on his knees. "Our precious Scooby snacks are gone!"

"WE'RE DOOOOMED!" Scooby howled.

"Nobody is doomed!" Frankie said. "Shaggy, Scooby, you guys don't need treats to be brave. We need everyone's help to catch the thief! Will you help us? Please?"

"Pleeeeease? Pretty please?" Draculaura said. Her lip quivered and her lavender eyes got big and watery. Frankie joined her in making the big puppy dog eyes too.

Scooby whimpered, "Ruh, roh, puppy dog eyes."

"And they're pretty powerful!" said Shaggy.

The monster puppy dog eyes became too much for Shaggy and Scooby.

"Okay, we'll help you." said Shaggy.

"Jeepers! I can't believe it!" Daphne said. "Shaggy and Scooby actually willing to go on a monster mystery without Scooby snacks?!"

"Like, don't rub it in." said Shaggy.

"Then let's split up, gang!" Fred announced.

"Whoa! Hold, up!" said Clawd. "Split up for what?"

"We're trying to catch the thief who's been stealing everyone's stuff!" Frankie told him. "Like my bracelet, Cleo's nail polish, Mr. Where's watch..."

"Come to think of it, my new earrings has been missing too!" Clawdeen said. "I remember taking them off for gym class and the next thing I know, they're gone!"

"And my new necklace is gone!" Howleen said.

"See? No way this can all be coincidence." said Frankie. "So, we need to investigate!"

"That's what I'm trying to say!" Fred said, a bit impatient. "Like I said before, let's split up, gang!"

"Very well!" said Mr. Where. "Come, gentlemen. Let's investigate the Vampitheater!" He grabbed the dog and boy and dragged them along.

"Velma, you and I will investigate the ghoul's locker room." said Frankie.

"And we'll search the rest of the school!" Draculaura said with a salute. "And I know just where to start!"

So, the humans and monsters split up to find the thief.


Mr. Where brought Shaggy and Scooby to the Vampitheater. It was so dark and spooky.

"Zoinks! L-Like, why did we come here?!" Shaggy said.

"Because this is where I last saw my watch." said the invisible teacher. "Always start at the scene of the crime. Let us check backstage!"

As they followed the teacher backstage, Shaggy whispered to Scooby. "Y'know, Scoob. Maybe this Where guy is the thief."

"Ruh?" Scooby looked confused.

"I mean, think about it. When you're invisible, you can steal stuff right under everybody's nose!" Shaggy said softly.

"Rut what about his watch?" asked Scooby.

"Maybe he just said that so no one would suspect him!" said Shaggy.

Mr. Where turned. "Did you say something?"

"Uh, like, no! Nothing, Mr. Where, sir!" Shaggy fibbed. When the teacher turned his back, Shaggy leaned over to Scooby. "We need to keep a sharp eye on him, Scoob!"

"Rotcha!" Scooby saluted.

Mr. Where suddenly knelt down. "Hmm, this looks suspicious."

"What is it, Mr. Where?" asked Shaggy.

"There are claw marks on the floor." Mr. Where pointed them out and sure enough, there were scratch marks on the floor.

"A student with claws must have stolen my watch." Mr. Where pondered. "Perhaps it fell off my wrist and someone snatched it!"

"He must be trying to frame a student he doesn't like!" Shaggy whispered.

"Reah!" Scooby whispered back.

Mr. Where took out his phone and took a picture. "Our first clue! Now, we need to find which student took my watch...time for a little undercover work."

"Undercover work?" Shaggy and Scooby said.

"Yes, I will go invisible and find the student who's claw marks match these." Mr. Where said. "I'll let you boys know when I got something!"

And the invisible drama teacher disappeared.

"Huh?! He's gone!" Shaggy said.

They heard footsteps running off the stage and saw the door open and close.

"Great! Now how are we suppose to keep an eye on him?!" Shaggy said. "Our first suspect is gone!"

"Wait, you think Mr. Where is the thief?" a voice said in the dark.

"Rikes!" Scooby jumped.

"L-L-Like, who's there?!" Shaggy said. "We may not have Scooby snacks, but we've still got some bravado in us!"

"R-Reah!" Scooby said.

But the two didn't look so brave. And the person watching them could tell.

"Oh, really?" A girl emerged from the shadows. Her skin was a bluish-purple with pastel green hair. Her eyes glowed in the dark.

"AAAAAAAAAH!" Shaggy and Scooby screamed.

"A GHOST!" Shaggy wailed.

The girl shook her head. "I'm not a ghost, I'm a boogeyman."

"R-R-R-Roogeyman?!" Scooby stuttered. He and Shaggy tried to run away but another girl appeared. This time she came right through the wall!

"Wooo! So the rumors are true!" said the girl who was floating in mid-air. She had purple hair and wore a black and purple dress. And she was white and see-through!

"A REAL G-G-G-G-GHOOOOOST!" Shaggy screamed.

"AAAAAAAAAAAAAAAAAAAAAAAAAH!" Shaggy and Scooby's confidence crumbled and ran out of the room.

"Wait! Come back!" the ghost girl said, flying after them. "Come on, Twyla!"

"Spectra! Wait!" Twyla the boogeygirl said as she followed her friend.
