Sid felt bad.
"Sorry about your tower, Rex," he said.
Rex sighed. "It's okay."
He stacked rocks again.
Tor stopped playing.
"Our band is missing something," she said.
"What?" Sara asked.
"I don't know," Tor said.
"But we need something."
Sara shrugged. "I think we sound great."
She shook her seed pods.
Just then Rex made a soft roar.
"I finished my tower!"
"That's it!" Tor cried.
"Huh?" Rex was confused.
"Our band is missing you, Rex," Tor said.
"You can roar!"
Rex smiled. "Okay!"
The buddies played music together.
Rex roared as Sara shook her seed pods.
Tor played her flute.
Sid slapped his tail.
But he wasn't careful.
Wham!
Rex's tall tower fell down.
Sid grinned. "Oops."
Everyone laughed—even Rex.
