"I'm bored," Sid said.
Sara nodded. "There's nothing to do."
Tor found a ball in her bag.
"Let's play catch," she said.
"That sounds fun," Rex said.
Just then a rat ran by.
It slipped under a leaf.
"Look!" Sara said.
A hole was beneath the leaf.
The rat dived in.
Sara peeked into the hole.
The rat got mad.
Squeak! Squeak!
Sara jumped back.
"The rat lives in there," Rex said.
"Its home is like a tiny fort."
Sara smiled.
"Let's build our own fort!" she said.
"That will be fun!" Sid said.
Rex and Tor got some big sticks.
Sara and Sid worked on the fort.
"We need more sticks!" Sara said.
Rex carried lots of sticks.
"Wow," Sara said.
"You're strong, Rex!"
Rex grinned. Roar!
Crash! The fort fell over.
