Geo Umizoomi, the brave blue superhero with his trusty shape belt, explores the playground alone, humming a tune while checking UmiNumeral patterns on the equipment. The air is crisp and filled with the distant hoot of an owl, heightening the sense of adventure. Suddenly, a translucent white figure floats from behind a slide, its hollow eyes glowing faintly in the moonlight. Geo freezes, his small heart pounding as the ghost lets out a chilling wail that echoes through the empty park. "Aaaah! A ghost! It's real, and it's coming for me! I have to get away—help!" he screams, bolting across the dewy grass.

Geo runs breathlessly, glancing over his shoulder at the pursuing ethereal glow bobbing unnaturally through the night. His shape belt jingles wildly with each stride, patterns flashing in alarm. Sweat beads on his forehead despite the chill, his mind racing with fear of the supernatural pursuer. He dashes past glowing porch lights and shadowed bushes that seem to whisper threats.

Milli, the pink-patterned friend with her measuring band, and Bot, the green robot with spinning screens and bouncy wheels, sit playing a pattern game on the rug. The door bursts open, flooding the room with night air. Geo tumbles in, slamming it shut, his face pale and eyes wide with terror. "Milli! Bot! You won't believe it—a ghost chased me from the playground! It was all white and floaty with scary eyes, wailing like crazy! It followed me the whole way; we have to hide or fight it with UmiMight!" "Whoa, Geo, slow down and tell us everything from the start. A ghost? That sounds super spooky, but we're Team Umizoomi—we solve big problems together!"

Bot activates his screens, displaying playground maps and ghost sketches. Milli wraps her measuring band reassuringly around Geo's shoulder. They lean in close, voices determined, planning their investigation step by step. "Don't worry, buddy! My sensors detect no ghosts usually, but let's pattern-match what you saw. Describe the glow, the sounds—maybe it's a Umi-trick we can measure and fix with super math powers!" "Thanks, guys. It was tall, misty, with arms waving like it wanted to grab me. The wailing was 'Oooooh' super loud—we need to go back and use shapes to trap it!" "Perfect plan! We'll measure its size, Bot scans for clues, and Geo patterns the escape. Team Umizoomi, activate UmiMight!"

The team creeps forward cautiously, hearts racing but united, scanning with gadgets. Bot's wheels splash through puddles as he beeps detections. Tension builds as rustling sounds emerge again. "Look—white sheet on the bush, and footprints leading here! Not ghost tracks; they're sneaker prints, size small like a kid's. This ghost is wearing shoes!" "You're right! And listen—no wailing, just giggling now. It's not a real ghost!"

Timmy, the neighborhood kid with freckles and a prankster gleam, stands up, sheet draped comically over his head. The team surrounds him gently, flashlights dimming as relief washes over their faces like the fading fog. "Okay, okay, it was me! I wanted to scare everyone for Halloween practice, but I didn't mean to freak you out so bad, Geo. Your running was super fast—I chased to say sorry, but the sheet muffled my voice!" "Timmy, that was terrifying, but I'm glad it's just you. No more ghost pranks—let's use UmiNumbers to plan real fun instead!" "Yeah, teamwork beats tricks every time. Friends help friends, even pranksters!"
