Dora, the brave young explorer with her signature pink shirt and orange shorts, leads the way with a big smile, her backpack filled with maps and snacks. Boots, her loyal monkey friend wearing red boots and a green backpack, swings from low branches, chattering excitedly about their adventure. "¡Vamos, Boots! This forest has so many amazing things to discover today, like hidden caves and sparkling streams—we're going to find them all before the stars come out!" "Hee hee, yeah Dora! I love exploring with you, especially when we sing our traveling song to keep the rhythm going!"

Dora freezes mid-step, her eyes widening as a translucent white shape materializes from the fog ahead. Boots clings to her leg, his fur standing on end, tail tucked tightly. "Boo!" booms a deep, ghostly voice from the figure, its hollow eyes glowing faintly in the gloom. "¡Ay, caramba! A ghost! Run, Boots, run for our lives—it's real and it's coming right for us!" "Eek! Ghost! Too scary, Dora—my boots are shaking, let's get away fast before it catches us!"

Dora grabs Boots' hand, pulling him along as they leap over roots and dodge low-hanging vines. "Dora, it's still chasing us—I can hear the boo sounds getting closer; what if it haunts us forever and we never see Backpack or Map again?" "Don't worry, Boots, we'll find help soon! I remember there's a UmiCity portal nearby—maybe Geo and the Umizoomis can use their math powers to save us from this spooky ghost!" Their breaths come in gasps, the chase building relentless tension.

Dora and Boots tumble through, landing in the bright, geometric world of UmiCity, where buildings pulse with colorful numbers and shapes. Geo, the young math whiz with his orange mohawk, blue glasses, and UmiAlarm on his belly, looks up from tinkering with pattern blocks, flanked by his robot cat Bots. "Geo, Umizoomi! We were in the forest and a scary ghost jumped out yelling 'boo'—we ran all the way here because it was chasing us with glowing eyes and everything!" "Yeah, it was super spooky—please help us figure out what to do, or it might follow us even here!"

Geo adjusts his glasses, activating his UmiAlarm with a confident press, as Bots meows and projects helpful diagrams. "Don't be scared, Dora and Boots—we Umizoomis are experts at solving big problems with super math powers! Tell us more about the ghost: was it tall, see-through, and did it move in straight lines or wiggly patterns? We'll use shapes, counting, and patterns to investigate and make a plan right now." "It was white and floaty, saying 'boo' really loud, but you're right—math always fixes things! Can we go back together and check it out?" "Yay, team UmiZoomi—let's pattern-power that ghost away!"

Geo scans with his tools, while Dora and Boots hold pattern cards. "Boo! Stay back, or I'll haunt you all night with my ghostly tricks—who dares challenge me in my foggy home?" "Not so fast, ghost! Look at this pattern on the tree—it's repeating shapes that match a costume disguise, not a real spirit. Dora, Boots, count the edges: four sides, like a sheet over something solid!" Dora gasps, stepping closer fearfully at first. "¡Espera! If we pull it gently... oh no, it's just..."

Swiper, the sly fox with his striped tail, mask, and sneaky grin, stands sheepishly, holding a boo-box. "Aw, shucks—you tiny adventurers and your math figured me out! I was just playing a Halloween prank to swipe some acorns without anyone noticing, but your patterns and counting were too smart for my ghost trick." "Swiper! You scared us so much, but now we're all friends again—no more ghost games, okay? Let's share the acorns instead!" "Hee hee, that was fun once we knew—UmiZoomi rocks!" "Problem solved with super math—high five, team!"
