"Man, that is one steep drop, Scooby-Doo," Shaggy told his best friend. "I wonder how far down it goes?"
"I don't know." Scooby replied.
The cowardly duo listened to Scooby's echo before noticing that everyone left them behind.
"Like, hey, where did everybody go?!" Shaggy yelped before running to catch up with the group. "Wait for us!"
"Nobody move," Amelia told the others as she had the first look with her flashlight. "This is the first trap."
"Jeepers! That doesn't look like Cleopatra." Daphne commented.
"That's because it isn't, it's the Egyptian goddess Isis." Diana clarified.
"Her power protects Cleopatra's tomb." Dr. Quest added.
"She married her brother Osiris." Cindy added.
Penn glanced in disturbance of that fact.
"Ancient Egypt, Penn." Cindy shrugged in defense.
"Like, gangway!" Shaggy yelled out as he soon came in running with Scooby.
"Shaggy, Scooby, wait!" Haley cried out.
"Stop!" Hadji added.
Shaggy and Scooby tried to stop only to slide into all of the others, moving them towards the floor of Isis and Scooby stepped on a tile which crackled it.
"Guys, don't move!" Jonny told the cowardly duo. "The floor is a trap!"
"Just our luck, Scoob," Shaggy frowned. "Out of the frying pan and into the microwave!"
The floor cracked even more, destroying the floor.
"MOVE!" Jessie told them.
Everyone soon ran away as the floor began to crack more and more.
Haley was running with the group, but Amelia smirked, sticking her leg out, making the redheaded girl trip. "Hey, you bitch!" she then glared at the woman.
"Takes one to know one, doesn't it?" Amelia smirked.
Haley smirked back, and grabbed the blonde woman's leg and pulled her down too. "You got that right."
Shaggy and Scooby fell in before they soon jumped out and ran after the others to avoid the trap. Jonny then helpedd Haley up which made her blush.
"Thank you."
"No problem." Jonny told her.
Haley blushed and follows the others to safety
"Safety First." Mike told the others before she saw that she was missing a shoe.
Everyone then managed to get out of the room before it was destroyed altogether.
"Where's Shaggy and Scooby?" Brianna wondered.
Shaggy fell on the floor with Mike's missing shoe before sitting up and looking around. "Scoob, where are you?" he then asked.
There was a sarcophagus shown with an OUT TO LUNCH sign in front of it. Shaggy then opened the door and found Scooby with an Egyptian headdress as he ate a sub sandwich.
"Well, how do ya like that?" Shaggy smiled. "Instead of King Tut, I found King Mutt!"
"King Mutt!" Scooby smiled back and laughed at the joke.
"Guys, are you okay?" Daphne asked.
"Yeah, we'll be a whole lot better if we have more sandwiches." Shaggy said.
"They're okay." Mike said flatly.
"Like, Mike, we have your shoe too." Shaggy then told the tomboy, finding a red and white sneaker.
"Just throw it, I can catch it." Mike replied.
Shaggy then threw the shoe toward Mike.
Mike held out her foot and put the shoe back on. "Thanks, Shag." she then said.
"This way." Amelia commanded and her crew soon followed her as their boss.
"Shaggy, Scooby, stay right there." Trent said.
"We'll be back to come and get you." Cindy added.
"So much for not splitting up." Shaggy told Scooby.
"Reah..." Scooby frowned.
Amelia's crew soon arrived in front of a statue of a certain princess.
"Hold on, we've got something here." The strong man said.
"There's movement all around us." The woman added.
"This might be complicated." Cindy warned the others.
"Cin, you worry too much," Penn told her. "We've got this in the bag."
"I don't like this, Doc." Race muttered.
"I don't like it either, Race, but we gotta make sure that Dr. von Butch doesn't take the golden crown or the ankh necklace." Dr. Quest told his bodyguard.
"As long as you say so." Race sighed to him.
"Greeeaaat..." Dr. Venture groaned. "First that desert storm, then that prince gets turned into stone, and now all of this is happening. What's next, we get a visit from The Ghost of Cleopatra?"
Brock just rolled his eyes slightly at his boss.
Meanwhile with Shaggy and Scooby...
"Whoa, look at all these creepy coffins," Shaggy said to Scooby on the way down. "Hey, Scoob, you know who tucks a mummy into bed at night?"
"Ruh-uh." Scooby shook his head.
"Her mummy." A voice replied.
"Zoinks!" Shaggy gasped. "Who said that?!"
"Shaggy, is that you?" The voice asked.
Shaggy and Scooby turned around. A little mummy girl with a pink hair bow soon came over to see them while giggling.
"Tanis!" Shaggy and Scooby smiled before running over and giving her a hug.
"Like, what are you doing here?" Shaggy asked.
"I live here with my big sister, Cleo." Tanis smiled.
"Uh, Cleo?" Shaggy and Scooby replied.
"Cleo, come on out, I want you to meet my old gym teachers!" Tanis called out.
"Tanis, you know we're not supposed to come out like this." A mummy teen came out to her sister.
"I know, but I wanted to see Shaggy and Scooby." Tanis smiled to Cleo.
A mummy teenage girl with jewels and bandages came out with a familiar bird hybrid woman. "Hello, I'm Cleo De Nile, and this is our helper: Harpie Lady." Cleo introduced.
"Zoinks! It's that bird that attacked Mike!" Shaggy panicked.
"Ah, so it's you again." Harpie Lady replied.
"Mike?" Cleo asked. "As in Mike Mazinsky?"
"Yes, mi'lady, I thought they were going to rob you since they nearly destroyed the tomb." Harpie Lady excused.
"How dare you try to attack Mike!" Cleo glared. "Mike is the nicest person I've met in 5,842 years!"
"I said sorry!" Harpie Lady glared back slightly.
"Take it easy, Cleo, Alois didn't know who she was." Tanis told her sister.
"Well... All right, but we'll have a word more about this later on." Cleo warned the harpy.
"Yes, ma'am." Harpie Lady obeyed.
"So, like, that bird chick won't hurt us?" Shaggy asked Tanis.
"Not as long me or Cleo say so." Tanis smiled.
A brown creature with eyes floated around Scooby, making him panic.
"That's my friend, Kuriboh." Tanis smiled.
"Ruiboh?" Scooby asked.
"Yeah, he's my best friend." Tanis nodded.
"That was the creature Cindy was talking about earlier, who she thinks is adorable." Shaggy memorized.
"Do Mommy and Daddy know you have company?" Cleo asked Tanis.
"Uh... No, I don't think so..." Tanis replied.
"They might be mad then..." Cleo replied nervously. "Also no doubt that Nefera told them."
"So, I guess you listen to this Nefara too, huh?" Shaggy guessed to Harpie Lady.
"I only serve Princess Cleo and Princess Tanis." Harpie Lady replied.
The other mummies soon came over.
"Now, now, settle down," Tanis told the other mummies. "These are my friends from Ghoul School: Scooby and Shaggy."
"Like, hi!" Shaggy said nervously. "We're friends with your cousins, nieces, or whatever!"
The other mummies growled and had their weapons out. Harpie Lady stood in front of Cleo and Tanis as she prepared to fight if the other mummies tries to attack.
"So, uh, Tanis, you're, like, a princess?" Shaggy asked the little mummy girl.
"Uh-huh!" Tanis smiled up to him. "Isn't it amazing, Shaggy? By the way, where's Scrappy?"
"He's, uh, with his mother for the time being." Shaggy told her.
"Oh, okay." Tanis shrugged.
The other mummies pulled out their weapons and approached towards the group.
"Stop it!" Tanis told the mummies. "These are my friends!"
The mummies didn't listen to the young mummy, and were about to attack her, but Cleo grabbed Tanis right before they could swing their ax at her.
"Are you okay?" Cleo asked her little sister.
"Yes, I'm fine, but why are they attacking?" Tanis pouted.
"I don't know," Cleo told her little sister. "I don't get it, they shouldn't be hurting us."
The other mummies were chasing after the cowardly duo who then ran off.
"Alois, help Shaggy and Scooby, but don't hurt the mummies!" Cleo called out.
"Yes, ma'am!" Harpie Lady commanded.
"Don't worry, Tanis," Cleo soothed her little sister. "We'll handle this together."
"Thanks, Cleo." Tanis smiled back.
Meanwhile, the group heard the cowardly duo's voices.
"Listen, it sounds like Shaggy and Scooby, and they're in trouble." Mike told the others.
"Guess what? So are we!" Cindy replied as she pointed before them.
The army of mummies soon appeared with weapons and surrounded the group.
"It's the army of the undead!" Hank cried out.
"Oh, shit." Dr. Venture muttered.
"DEAN!" Hank called out to his brother. "GET 'EM!"
"You know it won't work unless I'm angry..." Dean said uneasily.
The mummies then attacks the group Mike, June, Dee Dee, The Eds, Trent, Brianna, and Cindy used their powers while Haley, Brock, Race, Hadji, Jonny, and Jessie used their fighting skills. Jonny looked over as Haley was fighting against the mummies
"Wow... She's good..." Jonny commented about Haley.
"You can do it, Cindy, just think about what your grandmother would do!" Mike coached.
"I'll try, Mike!" Cindy called back.
The mummies were chasing after the little girl until she made a set of bow and arrows to attack the mummies.
"Hey, I did it!" Cindy then smiled.
"Way to go, Cindy!" June gave a thumb's up.
"Heh, I'm getting the hang of this." Cindy chuckled.
"Dean, come on, get angry." Hank coached.
"But I'm not angry, Hank, just scared." Dean replied.
"Um... Imagine if Gi was right there, and she was just being attacked by the undead." Hank suggested.
"I don't know if I can do that." Dean rubbed his arm shyly.
"For crying out loud, Dean!" Hank complained. "Just change, dammit!"
Dean was about to say something, but a couple of mummies tackled him, putting a sword on his neck.
"Dean!" Hank yelped.
The mummies laughed as they were about to cut Dean up with their sword.
"Hang in there, buddy; I'll save you." Hank said as he was about to go and save his brother, but two mummies grabbed a hold of him and were about to slice him with their ax.
"Hey, let go of my brother!" Dean demanded.
The mummies didn't listen to him, and just laughed.
Dean snarled as he was soon going to become the werebeast even if he didn't want to.
"Get off of me, you undead mummies!" Hank demanded.
One mummy had the ax close to his neck while laughing. Dean soon shook as he then roared like a true beast and began to fight against the mummies to save Hank. He may had been a pain, but he was still his brother.
"Jeepers! What is that?!" Daphne gasped and pointed to Dean who was fighting the mummies.
"That's a werebeast, don't worry though, Velma, it's just Dean, he won't hurt ya, I guarantee it." Mike promised.
"Oh, shit, Dean transformed." Brock muttered.
"Don't worry, Dad, he'll remember us..." Haley said. "...I hope."
Dean soon snarled as he fought against the mummies while everyone else got out of the way.
"Dr. Venture, how did your son even become a creature like that?" Dr. Quest asked.
"Well, I, uh, made a drinking formula that can change anyone into any creature." Dr. Venture replied.
"You made your own son drink that?!" Diana's eyes widened.
"No, he did it himself," Dr. Venture defended. "He thought it was just plain old juice."
"Why didn't you stop him?!" Diana glared slightly.
"I tried, but... It was too late." Dr. Venture smiled nervously.
"How could you do something like that?!" Diana asked.
"Hey, at least he doesn't kill anyone," Dr. Venture said. "Hank and Haley often control him just in case he does something crazy or stupid."
"Ugh..." Diana groaned. "And I thought the Netherworld's rules were ruthless."
"Hey, I'm trying to make a cure," Dr. Venture said. "Keyword: trying."
"I guess we'll give him that one..." Diana deadpanned. "You just better hope he doesn't kill anyone that isn't already dead."
"Don't worry, Hank and Haley are in charge so that he doesn't go on a killing spree." Dr. Venture reassured.
"If you say so." Diana muttered.
"What is that?!" Hadji asked.
"That's Dean, he's a werebeast." Haley said.
Dean snarled as he attacked the mummies.
"Jinkies!" Velma gasped. "I can't believe that your friend is a werecreature, Haley."
"I forgot to tell you guys." Haley said.
"Don't worry, he's not gonna hurt anyone, unless you're a threat, because a pain in the ass like Haley gets off easy." Hank teased.
"Watch it, Ascot Boy, or I'll kick your ass!" Haley warned.
Hank blew a raspberry to her.
"That's it!" Haley glared and soon tackled him.
Amelia gasped and backed up nervously to both her woman and strong man. "Natasha, Campbell, what is that creature?!" she then demanded to know.
"That is the werebeast, I'll find out more research if I can." Natasha replied as she took a look at her computer.
"Shall I get rid of it, Dr. von Butch?" Campbell replied.
"Maybe that would be best." Amelia replied.
"Don't!" Dr. Venture told her. "That may be a beast, but that's my son!"
The mummies were behind the cranky doctor and soon dragged him away.
"Oh, shit, Doc!" Brock panicked.
"Get your hands off of me!" Dr. Venture demanded. "This is a cotton shirt!"
The mummies didn't even care and just took Dr. Venture away. Brock soon ran over to save his boss only to be surrounded by even more mummies.
"Dad!/Dr. Venture!" Hank and Haley cried out for the doctor.
"Come on, Cindy, let's get help." Penn told Cindy.
Cindy nodded and followed him before they got stuck and seemed to sink.
"Is the ground lowering or is the world rising?" Penn asked.
"Hey, Uncle Penn, lemme ask you something," Cindy said. "What is it that's not exactly water, and it ain't exactly Earth?"
Cindy and Penn were soon shown from their shoulders up and yelled out together. "QUICKSAND!"
"HELP!" Cindy cried out.
"Yeah, save me!" Penn added.
The mummies heard those two screaming and ran over, then grabbed their collars so they wouldn't go anywhere.
"Oh, hey, thanks," Cindy said before she saw the mummies. "I mean, 'AAAH!'"
"Cindy, do something!" Penn cried out.
"I am doing something!" Cindy told him. "I'm panicking!"
"Cindy, do you know how to swim in quicksand?" Penn asked.
"Uh, I don't know if that's humanly possible..." Cindy shrugged.
"We're doomed, aren't we?" Penn asked her.
"I'm afraid so." Cindy said.
"Harpie Lady, attack those mummies, but remember, don't kill them." Cleo's voice ordered.
"Huh?" Penn and Cindy blinked.
Harpie Lady soon went to do what Cleo said since she served under her and Tanis's parents.
"Oh, my God, Cindy, it's that bird lady from before!" Penn said.
"Drop them." Harpie Lady glared to the mummies who had a hold of Penn and Cindy.
The mummies growled and approached to the duel monster who got ready to attack.
"Don't worry, you guys, we're going to help you." Cleo promised.
"And I know just the right person," Tanis said as she soon pulled out a slab which a picture of a woolly mammoth made out of bones. "Mammoth Graveyard, I summon you to help out our friends!"
"What's with all the Yu-Gi-Oh references?!" Penn asked.'
"Foreshadowing?" Cindy shrugged.
"Hey, you think they're going to summon that Dark Magician Girl?" Penn asked. "She is pretty hot."
"She is pretty cute." Cindy had to agree.
Penn glanced to her with a smirk.
"Leave me alone!" Cindy glared in defense.
A mammoth grabbed a hold of the two and pulled them out of the quicksand.
"Too tight!" Cindy yelped.
"Hey, look, it's Manny from the Ice Age movies!" Penn laughed.
"It's not Manny, Penn, it's a duel monster called Mammoth Graveyard!" Cindy told him.
"It was a joke, Cindy," Penn deadpanned. "Man, for a genius girl, you sure are dumb."
"Hey, I'm not the one who thought that my cereal was talking to me." Cindy deadpanned.
"My spoon said 'OOOO', what do you think that means?" Penn defended.
"Those were Cheerios, not Alpha Bits." Cindy deadpanned.
"Are you guys okay?" Cleo asked the two.
"Why do you have Duel Monsters serving you?" Penn replied.
"Um, because I'm a princess?" Cleo replied like it was obvious.
"Well, that makes sense since duel monsters do serve under Pharaohs and their families," Cindy said. "That's really cool."
"I guess you could say that," Cleo replied. "I'm doing it, and so are my sisters."
"I didn't know Tanis was your sister though, I mean, I just recently found out that Winnie and Clawdeen are sisters." Cindy shrugged.
"Well, we don't really see each other much since she's a student in Ms. Grimwood's school." Cleo replied.
"But soon I'll go to Monster High with my friends and we'll be learning the next step in our after lives as young monster women!" Tanis cheered.
"Yes, you will, and you will learn a lot more once you graduate from Ms. Grimwood's school." Cleo smiled down to her little sister.
"I love Ms. Grimwood," Tanis smiled. "She made me my own trophy case."
"Hmm... There must be something in the Yu-Gi-Oh book about this." Cindy said to the mummy sisters.
"That must be pretty cool to have duel monsters serving you." Penn added.
"I suppose it's a living." Cleo replied.
"Hey, thanks for saving our butts." Penn said.
"Otherwise we would've been mummy food." Cindy added.
"It's a blessing..." Cleo replied. "Though I think my curse might be my older sister."
"Nefara is such a bully." Tanis pouted.
"Especially when she kissed my ex-boyfriend right in front of me!" Cleo scowled.
"Drama~..." Penn rolled his eyes. "Sisters."
"Oh, come along now, not all sisters are that bad..." Cindy told him.
"Mine is dead, Cindy." Penn reminded.
"Yikes! Sorry, I forgot." Cindy said.
"Uh, guys, like, I hate to interrupt you all, but the floor is cracking." Shaggy said.
"Get in the coffin!" Tanis cried out.
They all gone into the coffin, and they took off after the floor cracked.
