They found Ryan the rhino.
"We need your help," said George.
They told Ryan the story of Roy and Lucy.
"I love an adventure!" said Ryan.
"Let's go!" said Roy. "We must hurry."
Ryan tried Zed's roller skates.
He had never been so fast.
"Whoo wee!" shouted Ryan.
On they went to rescue Lucy.
Someone took a photo.
There was a story in the newspaper.
There was a story on TV.
On the road they could go even faster.
It was dark when they arrived and there was a full moon.
Their clock was ringing.
They could hear Lucy's clock ringing too.
Mango stood on Lucy's trunk.
"Can you see them?" asked Lucy.
Mango waved at Roy. "Get ready," said Mango.
Ryan got ready for his part.
He rolled down the hill.
Crash! Ryan crashed through the zoo wall.
"Let's go!" cried George.
"Let's rescue Lucy!" cried Roy.
They all ran down and into the hole in the wall.
"Where's Lucy?" asked George.
Ryan had crashed into the wrong cell.
"We're trapped!" cried Roy.
