"Oh no!" said Detective Smith.
"That monster will destroy the Metro City Convention Center!
We must . . . Rocket Girl?"
Roxy landed in front of the Metro City Convention Center.
The building's roof was gone.
Broken glass and bricks were everywhere.
People ran out of the building.
"A monster ate my flowers!" cried a man.
"Run for your lives!" shouted a woman carrying an empty flowerpot.
Rooaarr!
The ground shook.
A shadow fell over the convention center.
A huge monster stood up from behind the building.
The monster had green scales and a long tail.
It looked like a giant reptile.
Roxy gulped. "The monster is bigger than I thought!"
Rooaarr!
The monster reached into the convention center.
It pulled out a bunch of roses and ate them.
The monster burped loudly.
Then it turned and walked away from the convention center.
The monster sniffed and pulled all the flowers out of a garden.
Then it walked some more.
"I have to stop that monster!" said Roxy.
"It's headed for Mara's neighborhood!"
Roxy shot after the monster.
Whiz-hoo! She fired her eye laser beams.
The laser beams bounced off the monster.
The monster spun around. Rooaarr!
It batted Roxy, knocking her onto a roof.
The monster walked some more, sniffing and eating flowers.
Jack, Terrell, and Mara looked up from Mara's backyard.
"Whoa!" cried Jack.
"It's a huge monster!" cried Terrell.
Roxy flew after the monster.
"My eye laser beams didn't work," she thought.
"I need something else."
She spotted a big water tank.
She lifted it and shot toward the monster.
"Look!" shouted Mara. "Rocket Girl!"
Roxy threw the water tank at the monster.
The tank burst open.
Water dumped onto Mara, Jack, and Terrell.
Rooaarr!
"Uh-oh!" thought Roxy.
"The monster is angry now!"
The monster ran toward Roxy and batted her again.
Roxy ducked out of the way.
"Ha!" she said. "You can't . . . Whoa!"
The monster whipped its tail, knocking Roxy far away.
She landed with a crash on the other side of the city.
Roxy quickly flew back to Mara's neighborhood.
Now the monster was heading up into the mountains.
Boom, boom, boom! A mountain shook.
A boulder broke loose and started to roll.
Then another boulder broke loose, and another.
Soon lots of boulders were rolling fast down the mountain.
They were headed right toward some buildings.
"Uh-oh!" cried Roxy.
"Those boulders will smash into Metro City!"
