"I hope this doesn't fall," Rex said.
He was making a rock tower.
It was getting tall.
Sara ran over.
"Hey, Rex!"
Rex was surprised.
His arm bumped the tower.
The rocks fell.
Rex sighed.
"Sorry, Rex," Sara said.
"Do you want to play a game?"
"No, thanks," Rex said.
"I'm busy."
He stacked the rocks again.
Sara walked around.
"I'm bored," she said.
Sara picked up two seed pods.
She shook them.
Rattle, rattle, rattle.
"Ooh!" Sara smiled.
"I like that sound!"
Sara shook the seed pods again.
Rattle, rattle, rattle.
Rex groaned.
"I can't work on my tower," he thought.
"There's too much noise!"
Rattle, rattle, rattle.
Rex spun around. "Sara, stop!"
The tower fell over.
