DATE:
The Little Bear Who Lost His Roar
Barnaby was a little bear who lived in a cozy cave with his family. Barnaby loved to play. He loved to tumble with his brother and splash in the river. But most of all, Barnaby loved to roar!
His roar wasn't very loud yet, but it was his special sound. He would puff out his chest and let out a little, "GRRRRR!" His mom and dad bears would always smile.
One sunny morning, Barnaby woke up and tried to roar. "Grrrr...?" he tried. Nothing came out! His roar was gone! Barnaby felt a little bit scared. How could a bear be a bear without his roar?
Barnaby decided he had to find his roar. He peeked outside his cave. A friendly squirrel was chattering nearby. "Excuse me, Mr. Squirrel," Barnaby whispered. "Have you seen my roar? It's a 'GRRRRR!' sound."
The squirrel twitched his nose. "No, Barnaby, I haven't seen any roars today. Maybe it rolled down to the bubbly brook?" he squeaked.
Barnaby thanked the squirrel and headed to the brook. He looked under smooth stones and between tall reeds. No roar. He saw a wise old owl perched on a branch. "Excuse me, Mrs. Owl," Barnaby whispered. "Have you seen my roar?"
Mrs. Owl blinked slowly. "A roar, you say? Hmm. Perhaps it floated up to the tallest tree where the wind sings?" she hooted softly.
Barnaby sighed. He climbed the tallest tree, but his roar wasn't there either. He sat down sadly. He missed his special sound so much. Just then, a tiny mouse scurried past. It looked frightened by something in the bushes.
Barnaby saw a big, grumpy badger about to scare the little mouse! Without even thinking, Barnaby puffed out his chest and let out the biggest, loudest "GRRRRRR!" he had ever made! The badger was so surprised it tumbled backward and ran away.
Barnaby felt his chest rumble. His roar was back! He hadn't found it rolling down a brook or floating up a tree. His roar was inside him all along, waiting for him to be brave. The little mouse squeaked, "Thank you, Barnaby! You saved me!"
Barnaby smiled. He knew then that his roar wasn't just a sound; it was his bravery.
Detectives: Read carefully and look for clues!
