Kip shook the snow off his head.
"Who threw that snowball?" he asked.
Bird looked up.
Snowy branches were above Kip.
"Nobody threw a snowball, Kip," said Bird.
Kip wasn't listening.
He looked around.
"Maybe Frog threw it," said Kip.
"Frog is asleep for the winter," said Bird.
"The snow came from—"
"It was Squirrel!" said Kip.
"I think he's awake."
Bird sighed.
"We need a snow fort," said Kip.
"Then we'll be safe."
Kip made a wall out of snow.
"We don't need a snow fort," said Bird.
Kip kept working.
Soon Kip's snow fort was finished.
Squirrel walked over.
"Hi, Kip."
Kip frowned at Squirrel.
"Did you throw a snowball at me?" he asked.
"No, why?" asked Squirrel.
A strong wind blew.
Snow fell on Kip and Squirrel.
"Someone threw a snowball!" they both cried.
