"I have to find out what happened to Mayor Bloom!" thought Roxy.
She looked at her friends.
"Hey, guys," said Roxy.
"I forgot my lunch money.
I'll meet you at school."
"I can lend you some money," said Terrell.
But Roxy was already gone.
A moment later Roxy arrived at City Hall.
But the building had disappeared!
"This is really weird," thought Roxy.
"I'd better find Detective Smith!
Maybe he knows what's going on in Metro City."
Roxy flew to Police Headquarters.
"Oh no!" Roxy cried.
That building was gone too.
"Rocket Girl!" a tiny voice called.
"Huh?" Roxy looked around but didn't see anything.
"That's strange," she thought.
"I thought I heard someone say my name."
The voice called out again, "Rocket Girl!
I'm down here!"
Roxy looked down. "Oh!"
Detective Smith stood in the grass, next to a dandelion.
He was about a centimeter tall.
He didn't look happy.
Roxy smiled.
"It looks like you have a little problem, Detective Smith."
Detective Smith frowned.
"This isn't funny, Rocket Girl."
"You're right," said Roxy.
"Can you tell me what happened?"
"We heard a strange sound," said the detective.
"Police Headquarters began to shrink, and so did everyone inside.
I jumped out a window.
Then an enormous figure picked up the building and walked away!"
Roxy scratched her head.
"Metro City's new skyscraper shrank too.
But it doesn't make sense.
Why would someone shrink buildings?"
"I don't know," said the detective.
"But we need to find out.
I can't stay like this for—"
Suddenly there was a loud sound. Whirr!
Roxy spun around.
Another tall building was shrinking!
"Uh-oh!" said Roxy.
She looked down at Detective Smith.
"You stay here, Detective.
I'll find out what's going on!"
Roxy flew over Metro City.
She heard the sound again.
Whirr! Whirr! Two more buildings shrank and disappeared!
Roxy landed and looked around.
She used her super hearing to listen.
"Tee-hee!"
"That sounds like a young girl giggling," thought Roxy.
"The sound is coming from the other side of that parking garage."
Roxy flew to the top of the parking garage and looked down. She gasped.
A young girl in a space suit held a strange device.
She pointed it at the bear statue.
Whirr! The bear shrank!
The girl put it in her pocket.
"Whoa!" cried Roxy.
"That young girl is shrinking things and taking them away!"
