Ben floated toward the new wall.
Cautiously, he poked his head through.
On the other side, he saw two construction workers and a bag—filled with the stolen Egyptian jewels!
"Boo!" Ben shouted.
The startled thieves jumped. "The ghost!" one cried.
Both sprang to their feet and rushed out of a hidden door in the wall.
"Stop, thieves!" Ben called after them.
He floated after the workers as fast as he could.
Crash! Just then Gaby burst through the construction area.
The thieves were running for the front door, but Gaby tossed a big dinosaur bone in their path.
"Ahh!" The workers screamed and turned around.
They ran toward the Egyptian exhibit.
Winnie swooped after them on her broom. "I'll get them!"
"I'll try a halting spell!" Waldo waved his wand.
"Duck!" one thief cried as the spell sailed toward him.
The two thieves dove to the floor.
Winnie steered downward, zooming faster than Ben had ever seen her fly.
Crash! Her broom smashed into Uncle Tut's display case.
Shattered glass flew everywhere.
Waldo was waving his wand again.
This time a spell zapped Uncle Tut, still sleeping inside the case. Sha-zam!
The ancient mummy's body shook all over.
His eyes sprang open, and he let out an angry growl.
"Who dares to disturb my rest?" he snarled.
The two thieves were on the floor near the shattered display case.
"Help!" they screamed as the old mummy walked over and grabbed them.
Uncle Tut lifted both thieves at once and shook them hard.
"Do not disturb the king!" he commanded.
"We surrender!" the thieves cried.
"We confess to everything."
From inside her wrapping, Cleo was beaming.
"Wow, Uncle Tut!" she said. "It's great to meet you!"
The two museum guards suddenly raced into the room.
Mr. Freaky was right behind them, looking very upset.
"What in the world is going on here?" the principal cried.
Ben grinned and pointed to Uncle Tut.
The mummy was still clutching the thieves.
"Uh, guess what, Mr. Freaky?" Ben said.
"It looks like the mummy just wrapped up this case!"
After the police took the thieves away, Mr. Freaky sank down on a bench in the lobby.
"Everything is finally under control."
"The construction workers were mad because I wouldn't pay them more," Dr. Bones said.
"That's why they decided to steal the jewelry from the museum."
"They knew we were coming here on a field trip," said Ben.
"So they disguised themselves as zombies.
That way, monsters would get blamed for the theft.
Their plan almost worked!"
Dr. Bones looked grateful.
"Thank you, monsters, for helping to catch the thieves.
The jewels are very valuable to the museum, and I owe all of you an apology."
"Me too," Al Normal said sheepishly.
He looked at Winnie.
"You were right, young lady. Monsters are just like people."
"I hope not!" Miss Bungle burst out.
Everybody laughed.
Dr. Bones turned to the ancient mummy, who had an arm around his niece.
"I also want to apologize to you, Mr. Tut—er, Your Majesty.
We would not have put you in that display if we'd known you were a live monster."
"That's okay," Uncle Tut said.
"Ruling an ancient kingdom is exhausting—I needed a rest.
But now I have a lot of catching up to do. What century is this?"
Cleo gave him a quick hug. "Wait till you meet my brothers and sisters, Uncle Tut!"
"I'm sorry I was jealous of Cleo," Gaby whispered to Waldo.
"I thought the two of you were sneaking out together last night.
I should have trusted you."
Waldo smiled at her. "It's a good thing you did get suspicious.
You helped to stop the thieves."
Dr. Bones was talking on her phone.
A second later she clicked it off.
"I just spoke with Mayor Hubbletree.
We've agreed that this field trip was a huge success.
Oh, and I have more good news."
She flashed a smile at the monsters.
"I believe I've convinced the mayor to send students from People Place to Monsterville for an overnight adventure!"
All the monster kids cheered.
The skeletons started rattling their bones and chanting, "Field trip! Field trip!"
Mr. Freaky buried his face in his hands.
"When will these field trips end?" he moaned.
Winnie and Ben laughed.
"Poor Mr. Freaky," Winnie said sympathetically.
Ben nodded. A minute later he grabbed Winnie's hand.
Together they ran outside, where the school bus was waiting to take everyone back to Monster Academy.
"The field trip to People Place was fun," Ben thought.
"But there's no place like Monsterville!"
