A guard walked through Metro City Prison.
"Lights out," she called. "It's bedtime!"
In his cell Mr. Presto grumbled and climbed into bed.
Mrs. Wiggles and Dr. Odd were in nearby cells.
"I hate bedtime!" Mrs. Wiggles said.
The guard ignored the villain.
She walked around a corner.
Then she gasped.
There was a huge hole in the wall.
The guard shouted. "A prisoner escaped!"
"Where's Terrell?" Jack asked.
Roxy and Mara were waiting outside Jack's house.
"He's going to be a little late today," Roxy said.
"We can walk to school without him."
The three friends walked along the sidewalk.
"Why is Terrell going to be late?" Jack asked.
Mara chuckled. "He's probably at home, trying to figure out who Rocket Girl really is!"
Jack laughed.
Roxy grinned. "No, he's at a dentist appointment."
Soon they arrived at school.
As they reached their classroom, Roxy heard her watch beep.
"I'll be right in," Roxy said.
"I have to, um, use the restroom."
Roxy ducked around a corner.
"Mayor Bloom," she whispered.
"Is everything okay?"
The mayor looked confused.
"I'm not sure, Rocket Girl.
I think someone escaped from Metro City Prison."
"Who?" Roxy asked.
"I don't know," Mayor Bloom said.
"The guards spent the night checking cells.
All the prisoners are still there."
Roxy scratched her head.
"I don't understand, Mayor.
Why do you think someone escaped?"
"There's a big hole in the prison wall," Mayor Bloom said.
"It's very suspicious."
"Okay, Mayor," Roxy said.
"I'm on my way."
Suddenly the school doors flew open.
Shwoom! A loud humming sound filled the air.
Roxy closed her watch.
She felt an invisible force pulling on her.
Teachers and students flew by, as if a vacuum was pulling them.
Using her super strength, Roxy kept her feet planted on the floor.
Mara and Jack flew by.
"Ahh!" Mara screamed.
"Help!" Jack shouted.
Books, pencils, and papers dropped from backpacks.
The hallway was a mess.
A moment later everyone was gone.
"Yikes!" Roxy thought. "What's going on?"
"Huh?" Terrell said. "What happened?"
He was standing in front of Metro City Elementary School.
Papers and books lay on the blacktop.
The doors were wide open.
Terrell ran inside.
At the far end of the hallway, he saw Roxy dart into a restroom.
Terrell hurried down the hallway.
A second later the restroom door banged open, and Rocket Girl burst out!
