Dora, the brave young explorer with her signature pink shirt and backpack, leads the way with excitement sparkling in her bright eyes. Boots, her loyal monkey friend with reddish-brown fur and a yellow boots outfit, bounces alongside, swinging from low vines playfully. "¡Vamos, Boots! Let's find the magic bridge today – it'll be such an adventure through this beautiful forest!" "Hee hee, yeah Dora! I love exploring with you, especially with all these pretty flowers and yummy berries everywhere!"

Dora and Boots pause near a cluster of glowing mushrooms, their faces illuminated by the fading sun. Suddenly, a translucent white figure with hollow eyes and flowing sheets emerges from behind a massive tree trunk, letting out a chilling wail that echoes through the woods. "D-Dora! Look over there! It's a ghost! A real spooky ghost with big scary eyes and it's coming right for us – we have to run, run super fast!" "¡Ay, no! You're right, Boots, that ghost looks so frightening with its wavy arms and ghostly moan – let's get out of here and find help right now before it catches us!"

Dora grabs Boots' paw tightly, both sprinting with wide-eyed fear, leaves and twigs snapping under their hurried feet. "It's still behind us, Dora! I can hear its spooky whooshes and see its glow in the shadows – my heart's pounding so hard, we need friends to help us stop this scary ghost chase!" "Keep going, Boots! We'll call our amigos – Geo and the Umizoomi team will know what to do; they're super smart with their math magic and tiny powers!"

Dora and Boots burst into the clearing, collapsing near the orb which activates with a cheerful chime. Geo, the math whiz boy with orange hair, a tool belt, and glowing shape-pattern shirt, appears on the holographic screen alongside his tiny Umizoomi friends. "Geo! Umizoomi! We saw a ghost in the forest – it was white and waily and chased us all the way here; please come help us figure out what it was!" "Don't worry, Dora and Boots! We're zooming in right now with our Umi-alarm – tell us every detail about the ghost's size, shape, and where you saw it so we can use our pattern powers and math to solve this mystery together!"

Geo leads Dora and Boots, his tiny friends Milli (pattern girl with pink hair) and Bot (robot with screen face) assisting nearby. They discover footprints and a discarded sheet with eye holes near the tree. "See these pattern clues? The 'ghost' was just someone wearing a white sheet with cut-out eyes – the footprints match kid-sized sneakers, and the fabric trail shows it was dragged, not floating!" "Wow, Geo, you're right! No more scary ghost – it was a prank all along, and your math tools figured it out super fast!"

Dora hugs everyone, relief washing over her face. "Exactly, friends! It was your neighbor Swiper trying a silly costume to surprise you for a game, but he got scared of his own shadow and ran off – no real ghosts here, just teamwork and Umi-patterns solving the day!" "Gracias, Geo and Umizoomi! We were so frightened, but now we know the truth and can laugh about it – adventures are better with amigos like you!" "Yay! No more running – let's have a picnic and celebrate with berries and pattern games!"
