In a lush green forest, Marvin the monkey joyfully played with his shiny new toy truck.

When Ruby the rabbit hopped over and asked, 'May I play with your truck?' Marvin shook his head.

Soon, Felix the fox and Penelope the parrot requested a turn, but Marvin wasn't willing to share.

The animals all wandered away to play a game of jungle ball without Marvin, their laughter echoing through the trees.

Marvin clutched his truck but felt a growing sense of emptiness as he watched the others from afar.

When Marvin finally went over and asked to join the game, the animals paused and glanced at each other.

'Why should we play with you when you never share?' asked Penelope with a frown.

Marvin's ears drooped, and he looked down at his toy, finally understanding how his actions hurt his friends.

'I'm sorry,' Marvin mumbled. 'I was selfish. Can you forgive me?' The animals were surprised but nodded.

The next day, Marvin brought a box of toys to the clearing and invited his friends to share them.

The forest was filled with joyous cries as all the animals played together with the toys Marvin brought.

Seeing his friends' smiles, Marvin realized that sharing was the true key to friendship and happiness.
