Dora, the brave explorer with her orange shirt and backpack, leads the way with her monkey friend Boots, his red boots splashing through puddles. They laugh and swing from vines, discovering colorful flowers and hidden streams under the fading orange sunlight filtering through the canopy. The air hums with the calls of exotic birds, setting an adventurous tone for their evening hike.

Ghost appears suddenly, letting out a chilling wail that echoes through the trees. Dora and Boots freeze, hearts pounding as cold wind whips their hair. "¡Ay, Boots! Did you see that? It's a ghost! We have to be careful, but let's keep exploring to see if it's friendly." "Dora, it scared me! But okay, vamanos, maybe it's just lost like us sometimes."

Over the next hour, the Ghost startles them 100 times—flashing behind boulders, drifting from branches, and emerging from shadows—each encounter building their fear. Dora's wide eyes reflect the moonlight as she clutches her map tightly. "Dora, that's the 50th time already! It's following us everywhere in this spooky forest—those glowing eyes and that horrible moan make my fur stand up! What if it never stops?" "I know, Boots, it's super scary, but we can't let it win. We've faced big storms and tall mountains before—maybe there's a way to talk to it or find out why it's here."

Panic overtakes them after the 100th fright, and Dora and Boots bolt through the forest, branches snapping and leaves crunching underfoot. Their breaths come in gasps, faces pale with terror from the relentless hauntings. "Run, Dora, run! That ghost won't stop—it's right behind us with its cold breath and spooky laugh! We've got to find help before it catches us!" "Hold my hand, Boots! We'll make it to my cousin Geo's place—he's a math wizard and can figure this out with his mighty math powers!"

Geo[/@ch_4]'s glowing Umi-phone, tools and pattern blocks scattered on a workbench under a clear, starry sky.] Gasping and wide-eyed, Dora and Boots burst into the yard where Geo, the tiny math hero in his green hat and orange overalls, tinkers with gadgets. Geo looks up in surprise, his friendly face lit by the soft glow. "Geo! A ghost scared us 100 times in the forest—it kept appearing with wails and glowy eyes, chasing us until we ran all the way here! Can your UmiZoomi powers help us understand what's happening?" "Yeah, it was the scariest thing ever—100 times! We need your super math skills, primo!" "Don't worry, Dora and Boots! We'll use patterns, shapes, and counting to solve this mystery. Tell me every detail while I grab my Umi-tools—together, we're UmiZoomi strong!"

Geo, with Dora and Boots, returns using math patterns to track the "ghost's" movements, pinpointing it near the ancient stump. They confront Ghost, who reveals himself as Sammy the Prankster, a local kid in a sheet with face paint and a hidden speaker for sounds. "See? By counting the 100 appearances and mapping the pattern—like every 10th time near this tree—we figured it's not a real ghost but Sammy playing a big trick! Great job, team!" "Sorry, guys! I just wanted to have fun, but I didn't mean to scare you that much—100 times was too many! Let's be friends and explore for real now." "We forgive you, Sammy! Adventures are better with friends, no more pranks though." Laughter fills the air as the forest feels warm and safe again.
