Once upon a time, in a big green garden, Cat and Bird were the best of friends.

One sunny day, Bird said to Cat, 'I need your help to build a nest for my babies.'

Cat jumped up with excitement and replied, 'Of course, Birdie! I'll help you build the best nest ever!'

They gathered twigs, leaves, and feathers from all around the garden. Cat climbed the tree and passed everything to Bird.

After a lot of hard work and teamwork, the nest was ready. It was cozy, warm, and safe for Bird's babies.

Suddenly, Cat noticed something. 'Birdie, there's something missing!' Cat said, feeling guilty.

Cat had forgotten to put a soft lining inside the nest. 'I'm so sorry, Birdie. I made a mistake,' Cat confessed.

But Bird smiled and said, 'It's okay, Cat. We can fix it together.'

They flew all around the garden, searching for soft grass and fluffy feathers. Finally, they found everything they needed.

Back at the nest, they carefully placed the soft lining inside. Now it was perfect.

As the sun started to set, Bird snuggled into the nest. Cat curled up nearby to keep Bird warm.
