Dora, the adventurous girl with a bright pink shirt and backpack, skips toward the school entrance alongside Franklin, the wise turtle wearing his signature blue hat and carrying his shell like a trusty shield. Their teachers, Miss Martinez, a kind woman with glasses and a flowing skirt, and Mr. Jenkins, a tall man with a mustache and clipboard, wave them over for a special after-school project. The group gathers near the front doors, chatting excitedly about exploring the old library wing.

Dora leads the way, flashlight in hand, as Franklin peers cautiously around stacks of books. Suddenly, a translucent white figure materializes at the end of the hall, moaning eerily with glowing eyes and tattered sheets billowing like mist. Miss Martinez gasps, dropping her books, while Mr. Jenkins freezes in terror. "¡Ay, un fantasma! It's a ghost! We have to run, everyone—fast, before it gets us!" "Oh no, this is worse than any storm I’ve ever seen! My shell won't protect me from that thing—let's get out of here right now, Dora, teachers, hurry!" "Children, stay calm, but yes, run towards the playground—don't look back, it might follow us through the shadows!" "I've never believed in ghosts until now—this school has secrets, but not like this; move, move, everyone, to safety!"

The group bursts out the doors, hearts pounding, as Dora grabs Franklin's paw, pulling him along while Miss Martinez and Mr. Jenkins usher them forward. They huddle behind the slide, breathless and wide-eyed, whispering about the horror they just witnessed. Dora remembers her friend from Umi City and pulls out her phone. "We need help—Geo from Umizoomi! He can use his shapes and math to figure this out. Franklin, teachers, let's call him right now and tell him everything about that scary ghost in the hallway." "Yes, Dora, Geo's gadgets are perfect for mysteries like this—he'll zoom in with his team and save the day, just like he does with numbers and patterns everywhere."

Geo, the math whiz with his orange hair, green shirt, and trusty shape belt, appears via video call alongside Milli, the pattern expert with ponytails and a yellow dress, and Bot, the friendly robot with glowing blue eyes and extendable arms. They listen intently as the story unfolds. Geo nods, activating his UmiAlarm. "Don't worry, Dora and Franklin—plus your teachers! We've handled spooky stuff before with super shapes and math. Tell us every detail about the ghost: its color, size, where it appeared— we'll pattern-match it and zoom over to investigate right away." "Yes, my patterns will spot if it's real or a trick—describe the sheets, the moans, everything, and we'll friendship-squeeze this mystery away together!" "Beep bop! Bot's ready with tools and lights—let's math our way to the truth and make the school safe again for playtime!"

Geo, Milli, and Bot arrive, high-fiving Dora and Franklin as the teachers watch in awe. They enter the hallway together, using shape finders and measuring tapes to scan for clues—odd footprints, a projector hidden behind a bookshelf. Tension builds as they approach the ghost's spot. "Look here—a string puppet setup and a fan for the sheets! No ghost, just someone playing a prank with math-hidden wires and angles we can calculate to prove it." "Phew, my heart was racing faster than a turtle in a race—thank you, Geo, for using your super math powers to uncover the truth!"

Janitor Sam[/@ch_8], a mischievous older man with overalls and a sheepish grin, caught red-handed with ghost props scattered around. Laughter echoes as relief washes over the group, moonbeams streaming through windows like spotlights.] Janitor Sam confesses it was a Halloween joke gone wrong, meant to surprise empty halls. Hugs and apologies fill the air, turning fear into friendship. The school feels safe again, ready for tomorrow's adventures. "Janitor Sam, you scared us good, but now it's all okay—thanks to Geo Umizoomi and friends for helping us see it was just a prank all along!" "What a night—lesson learned about bravery and teamwork; let's all promise no more spooky surprises without warning." "UmiZoom to the rescue once more—math and shapes solve everything, even ghost mysteries!"
