Dora's friends, [@ch_1]Benny, Isa, and Tico[/@ch_1], laughed and played tag around the picnic area, their colorful clothes bright against the earthy tones, while birds chirped overhead and distant mountains loomed under a clear blue sky. "This is the best picnic ever! Let's play hide and seek next," Benny shouted excitedly, his monkey tail swinging as he darted between trees. "Sí, and I'll hide the best! No one will find me in these bushes," replied Isa, her flower crown bobbing as she giggled.

Suddenly, a ghostly white shape with glowing eyes emerged from the mist, its tattered sheets billowing like spectral wings, causing the friends to freeze in terror amid the dimming light and crunching leaves underfoot. "¡Ay, caramba! A ghost! It's coming right for us! Run for your lives!" Tico squealed, his fur standing on end as he bolted, heart pounding. "I knew this forest was haunted! Help! We have to tell someone—Geo and the Umizoomi team!" Benny yelled, grabbing Isa's hand as they sprinted through the underbrush, branches whipping their faces.

Geo[/@ch_4], Milli, and Bot tinker with pattern puzzles under a starry sky.] Panting and wide-eyed, Dora's friends burst through the gate, their clothes disheveled and faces pale, collapsing near the friendly robot team who paused their math games. Geo, the young math whiz with his trusty map, looked up concernedly, while Milli with her stretchy bow and Bot with his screen face hovered helpfully. "Geo Umizoomi, you have to help! We saw a real ghost in the forest—it had glowing eyes and floated right at us! We ran as fast as we could, but it was so scary, like something from a nightmare," Isa explained breathlessly, trembling.

Geo and his team sprang into action, using super math powers to track footprints and measure spooky glow levels, leading everyone back through the whispering woods. "Look, the ghost's trail matches a pattern of sneaky steps—count the leaves: one, two, three... it's leading to that big oak tree! Umi-alarm!" Milli exclaimed, stretching her bow to point ahead. "Analyzing ghost data: 100% chance it's not real—probability of prank is super high! Let's solve this mystery together, friends," Bot beeped encouragingly, his screen displaying helpful graphs. "Great teamwork! Now, using my map, we see the ghost hid right... here!" Geo declared, pulling back a bush to reveal the truth.

Dora[/@ch_7], who peeks out laughing, backpack and map at her feet amid scattered prank props.] It was Dora all along, the adventurous girl with her signature backpack, giggling uncontrollably as her prank was uncovered, the "ghost" sheet fluttering down like a deflated balloon. "Surprise! It was just me practicing for a fun adventure story. I didn't mean to scare you so much—I'm sorry, friends! I thought it'd be a hilarious Halloween trick," Dora apologized, hugging everyone tightly. "Dora, you got us good! But next time, let's use math to plan safer pranks together," Benny laughed, relief washing over the group.

Boots[/@ch_8] swings in from the window sill.] Dora sat with her mom, Mami, recounting the tale on the plush couch, while nearby Boots, the playful monkey with red boots, listened wide-eyed before scampering to his sister. "Mami, I pranked my friends as a ghost, but Geo Umizoomi helped figure it out—it was all in fun, and we made up right away. I promise to be more careful next time," Dora confessed earnestly. "Sis, you won't believe it—Dora was a ghost today! She scared everyone, but the Umizoomi team saved the day with super math, and now we're all laughing about it. It was the wildest adventure ever!" Boots chattered excitedly to his sister, swinging from the curtains. "Oh, Dora, adventures are wonderful, but friends' feelings come first. Let's plan a real group exploration tomorrow," Mami smiled warmly, ending the night on a note of love and laughter.
