Little Bill clutches his backpack tightly as he hears a strange, hollow moaning echoing between the trees. The shadows seem to dance, and suddenly, a white, fluttering shape darts across his path. Heart pounding, Little Bill freezes, eyes wide, then bolts for safety, his sneakers pounding on the pavement. "A ghost! I saw a ghost! I have to get help!"

Little Bill[/@ch_1] doesn’t slow down until he spots a colorful, math-themed van parked nearby. Inside, Geo Umizoomi and his friends are working on a puzzle.] Little Bill bursts into the van, breathless and wide-eyed, startling Geo Umizoomi, who looks up with concern. "Geo, there’s a ghost in the park! It chased me — I swear I saw it floating!" "Whoa, don’t worry, Little Bill! We’ll figure this out together. Let’s use our Problem Solving Powers to get to the bottom of this mystery."

Geo Umizoomi[/@ch_2] carries a flashlight, and Little Bill stays close, nervously glancing around. The trees sway, and their shadows stretch across the grass.] Geo Umizoomi sweeps the flashlight beam around, looking for clues. "Let’s look for any signs of the ghost you saw. Was it making any noise or doing anything strange?" "It made this spooky moaning sound, and it was really fast! I just ran as soon as I saw it," Little Bill admits, peering into the darkness.

Geo Umizoomi approaches, pulling the sheet aside to reveal Bobby, Little Bill’s older cousin, grinning sheepishly. Bobby stands, brushing leaves from his hair, still holding the sheet. "Sorry, Little Bill! I was just playing a prank. I didn’t mean to scare you so much,"

Little Bill[/@ch_1] lets out a relieved sigh, his fear melting away.] "I really thought you were a ghost! You got me good, Bobby," he laughs, shaking his head. "See? Sometimes things aren’t as scary as they seem. We just need to look closer and stay calm," Geo Umizoomi says with a reassuring smile.

Little Bill thanks Geo Umizoomi for helping him face his fear. Bobby promises to prank more kindly next time, and together, they head home, ready for new adventures and a good night’s sleep.
