Dora, the brave young explorer with her signature pink shirt and backpack, leads the way with a bright smile, her map unfurled in hand. Boots, her loyal monkey friend with purple fur and red boots, swings from branch to branch, chattering excitedly. "¡Vamos, Boots! We're on a big adventure today in the rainforest, looking for hidden treasures and new friends. What do you see up there?" "Ooh ooh, ah ah! I see shiny berries and a funny-shaped rock, Dora! Let's go check it out together!"

Dora and Boots freeze as a translucent figure materializes from the mist, its hollow eyes glowing pale blue, tattered robes fluttering without wind. The ghost hovers silently, chains rattling softly, its form shimmering against the darkening purple sky dotted with emerging stars. "¡Ay, Boots! Look over there—what is that? It looks like a ghost from the old stories Abuela tells!" "Eek! Dora, it's scary! It's floating and glowing—run, run for our lives before it gets us!"

Dora grabs Boots's paw, both panting heavily, hearts pounding as they sprint through the underbrush, leaves crunching underfoot. The ghost's wail echoes behind them, distant but chilling, branches whipping their faces in the hurried escape. "We have to get help, Boots! Let's find my friends—they'll know what to do about this spooky ghost chasing us through the trees!" "Yes, Dora, faster! I don't want to be ghost food—tell them everything we saw, the glowing eyes and rattling chains!"

Geo, the tiny math wizard from UmiZoomi with his orange-striped shirt and yellow hair, tinkers with glowing shape tools beside Milli, his inventive partner with pink hair and a pattern skirt. Swiper, Dora's mischievous fox friend with his blue mask and striped tail, lounges nearby, no longer swiping but always ready for fun. "Geo, Milli, Swiper! Help! Boots and I saw a real ghost in the forest—it scared us so much we ran all the way here. It was floating with chains and glowing eyes—please, you have to help us figure this out!" "Yeah, it was super scary! We were exploring and poof—it appeared from the mist. What if it follows us?"

Geo activates his UmiAlarm, tiny gadgets whirring to scan data, while Milli sketches pattern clues on her loom. Swiper sniffs the air dramatically, his tail swishing. "Don't worry, Dora and Boots—we're UmiZoomi, and we'll use super math powers to solve this mystery. Let's measure the ghost's path and patterns to see where it came from—maybe it's not a real ghost at all!" "Exactly! I'll check for pattern repeats in the mist trails. Swiper, you scout ahead with your sneaky skills. Together, we'll pattern, count, and build our way to the truth!" "Oh man, a ghost? I'll swipe some clues if I have to—no swiping bad, just helping good this time. Follow me, amigos!"

The "ghost" unmasks, revealing a friendly park ranger with a white sheet costume, laughing heartily amid scattered props like fake chains and glow sticks. Tension melts into relief as stars sparkle overhead, the forest now friendly and inviting. Ranger Rosa, a cheerful woman with a green uniform hat and kind smile, waves apologetically. "Lo siento, friends! I was testing a new Halloween surprise for the park visitors, but I didn't mean to scare you for real. The fog machine and lights made it look so ghostly—forgive me?" "¡Qué alivio! It was someone all along, not a scary ghost. Thanks to Geo, Milli, and Swiper for helping us discover the truth—we make a great team!" "Yay! No more running—let's all have s'mores by the fire and laugh about our spooky adventure!"
