Rain fell hard.
The buddies were getting soaked.
Rex looked down at the river.
The river was moving fast.
"I see a tree," Rex said.
"Let's hide under it.
It has wide leaves."
"Good idea!" Tor said.
The buddies went down the hill.
The hill was steep and muddy.
The buddies slipped in the mud.
"Ugh!" Sid said.
"Eww!" Rex frowned.
"Mud went in my mouth!"
"Yuck!" Sara wiped mud off her face.
Tor sighed. "Now we're wet—and muddy!"
The rain poured down harder.
The rain washed the mud off.
"Yay!" Sara said.
The buddies sat under the tree.
"It's nice under here," Sara said.
Tor smiled. "It's dry!"
"Shh!" Rex said suddenly.
"I hear someone."
Everyone listened.
A voice cried, "Help!"
