Mayor Bloom was in trouble.
"Hey, guys," Roxy called to her friends.
"I'm going to . . . um . . . put more Car Wash signs up around town.
We need more customers!"
Roxy ran down the street.
"That's strange," thought Terrell, watching her go.
"Roxy isn't carrying any signs."
Roxy flew over to Police Headquarters Plaza.
There was a big empty spot where the police station had been.
"Rocket Girl!" called Detective Smith, waving from the ground.
Roxy flew down.
"Mayor Bloom is in trouble," she said.
"Oh no!" said Detective Smith.
"And Police Headquarters is gone!"
He started searching his pockets.
Roxy smiled.
"I don't think Police Headquarters is in your pocket, Detective."
"Very funny," said Detective Smith with a frown.
"I'm looking for my cell phone. Ah, here it is.
Look at this picture I took."
Detective Smith handed the phone to Roxy.
She saw a picture of a tall, silver robot.
"I was walking to Police Headquarters," said Detective Smith.
"Suddenly that robot appeared.
It sprayed a blue bubble around Police Headquarters.
Then the bubble floated away with the whole building in it!"
"Whoa," said Roxy.
"This looks like the work of Dr. Odd."
"You're right," said the detective.
"Dr. Odd is the only villain smart enough to invent a robot like this one.
But why did he take Police Headquarters and Mayor Bloom?"
"I know why," said Roxy.
"So the city can't stop Dr. Odd from stealing something else—like a bank."
A shadow moved across the street.
Roxy looked up.
Floating overhead were more blue bubbles!
Roxy shot into the sky.
Using her super vision, Roxy peered into the nearest bubble.
"That's Mayor Bloom's mansion!" said Roxy.
She struck the bubble as hard as she could.
Boing! Roxy bounced and landed far away, in another neighborhood.
"Ow," said Roxy.
Then she saw blue mist and jumped to her feet.
A car skidded around the corner and then bloop!
It was caught in a bubble and floated away.
More bubbles formed.
Bloop! Bloop!
They carried away cars, buses, people, and all sorts of other things.
"Uh-oh," thought Roxy. "I bet Dr. Odd's robot is—"
Crash! Boom!
Roxy looked up.
The robot stomped past her.
It stepped on a car and crushed it.
Roxy shot toward the robot.
But before she could reach it, the robot spun around. Bloop!
Roxy was trapped in a bubble!
