Geo Umizoomi strolls through the park, his eyes bright and curious. Suddenly, a cold gust of wind brushes past, and he pauses, sensing something unusual. He glances around, searching for the source of the chill.

Geo Umizoomi freezes, his heart pounding. The ghostly figure floats closer, its shape flickering between solid and transparent. "W-what is that?" he stammers, backing away slowly.

Geo Umizoomi spots his friend, Geo Martin, near the monkey bars. "Geo Martin! There's a ghost! I saw it by the willow tree!" he cries, his voice shaky.

Geo Martin examines the spot where Geo saw the apparition. "Let's take a closer look. Maybe it's not what you think," he suggests, kneeling to inspect the misty air. Together, they listen for strange noises and look for clues.

Geo Umizoomi and Geo Martin realize it's just another Umi City resident, dressed up for a prank. The person grins sheepishly. "See? It was just someone playing around," Geo Martin says, chuckling.

"Thanks, Geo Martin. I guess I let my imagination get the best of me," Geo says, smiling. The two walk off to join the others, ready for more adventures in Umi City—ghosts or not.
