Arnold the Rhino Dog was utterly unique, blending the body of a rhino with the head of a dog. Residing at the zoo, Arnold relished playing fetch and greeting guests with affectionate licks. One day, a group of children came to see him, buzzing with excitement. Arnold rushed over, and they played together for hours. When it was time to part, a tinge of sadness lingered, but they knew they'd reunite. Arnold waved farewell, already anticipating their next encounter.
