"I have to get to Metro City Central Bank," thought Roxy.
"Somebody is robbing it!"
She ran over to Mr. Green.
"Mr. Green," said Roxy.
"I just remembered something.
Principal Penn wanted to, um, talk to me."
"Go ahead, Roxy," said Mr. Green.
A moment later Roxy shot through the air.
"Look!" cried Mara. "Rocket Girl!"
Terrell scratched his head.
"Where did Roxy go?"
Roxy arrived at Metro City Central Bank.
Police cars surrounded the building.
The bank's front doors were smashed.
Smoke poured out of them.
A crowd of people stood across the street.
"Rocket Girl!" called Detective Smith.
Roxy flew over to the detective.
"Are you trying to deposit a check, Detective?" Roxy grinned.
Detective Smith frowned.
"This isn't funny, Rocket Girl.
A robbery is taking place!"
"I know," said Roxy.
"Is the bank robber still in the bank?"
Detective Smith nodded. "I think so."
"Do you know who he is?" asked Roxy.
A woman in the crowd stepped forward.
"Do you mean 'what' he is?"
Roxy was confused.
"I saw the robber," said the woman.
"He looks like a giant machine!"
"It's true," said a man in a suit.
"He's covered in big, heavy armor.
He looks like an army tank!"
"Hmm," said Detective Smith.
"This must be connected to the crime at Metro City army base."
"What happened at the army base?" asked Roxy.
"Somebody stole a tank," said the detective.
"It happened a couple of nights ago."
"I'm coming out!" shouted a deep voice from inside the bank.
"Everybody better stay out of my way!"
Detective Smith picked up a megaphone.
"The bank is surrounded.
Come out with your hands up!"
"Ha-ha!" The deep voice laughed.
"My name is Hank Tank, and I'm the toughest criminal in Metro City.
Nobody can stop me.
I'm coming out now with all the money I stole."
Roxy heard heavy footsteps inside the bank.
Stomp, stomp, stomp! The building and street shook.
People ran in all different directions.
"The robber is coming out!" shouted a woman.
"Run for your lives!" cried a man.
Detective Smith gulped.
"Hank Tank sounds pretty big."
"Yeah." Roxy nodded.
The footsteps stopped.
For a moment everything was quiet.
Then—ka-boom!
