Dora, the brave young explorer with her signature pink shirt and backpack, skipped along a winding path hand-in-hand with Boots, her loyal monkey friend wearing red boots and a purple vest. Suddenly, a rustle in the bushes made them freeze as a gang of mischievous villains emerged: Swiper the fox, the cute crook with his striped tail and sly grin, Maximo the elf, the shape bandit twirling geometric shapes, Zeta, the sorceress with glowing purple robes, Angelica Pickles, the bossy toddler in a yellow dress, Vicky, the mean babysitter with wild red hair, Candace, the frantic teen in orange, Rintoo the tiger, striped and roaring playfully, Minnie Mouse, polka-dotted and giggling, the pirate piggies, chubby swine in eyepatches and tricorn hats, Plankton the alien, tiny green menace with laser eyes, Olivia the pig girl, pink and curly-tailed, Kiki, the Fresh Beat Band girl with colorful streaks in her hair, Deema, the bubbly Guppy with fish scales, Orange Blossom, flower-powered and sweet, Fancy Nancy, frilly and fabulous, Vampirina, pale vampire girl with fangs, and Maggie and Miss Puff, the cloud fairy duo floating on wispy vapors. "Oh no, Boots! Look at all these sneaky swipers and baddies coming our way—they're blocking our path and looking super scary today!" "Yeah, Dora! They're growling and waving their tricks at us—we gotta run!"

Dora and Boots bolted through the underbrush, hearts pounding, branches whipping at their faces. Swiper swiped at the air with his paw, Angelica stomped her feet demanding attention, and Vampirina let out a playful hiss, making the chase feel like a nightmare. "Boots, we need help fast! Let's find Geo from Umizoomi—he's super good at fixing big problems like this with his math magic and tiny tools!" "Right, Dora! Tell him everything—the whole gang of them is after us, just like grumpy monsters on a spooky adventure gone wrong!"

Geo, the pint-sized Umizoomi builder with his orange hardhat and super gadget tools, appeared in a swirl of digital sparkles, ready for action. Milli and Bot, his pattern-loving sister and robot buddy, popped up too, their eyes wide with concern. "Geo, you have to help us! Swiper the fox, Maximo the elf, the shape bandit, Zeta, Angelica Pickles, Vicky, Candace, Rintoo, Minnie Mouse, pirate piggies, Plankton, Olivia, Kiki, Deema, Orange Blossom, Fancy Nancy, Vampirina, Maggie, and Miss Puff all scared us and chased us—they're a huge villain team today!" "Don't worry, Dora and Boots! We'll use our Umi-vision to pattern up some ghost costumes just like Bubble Puppy and Mr. Owl wore on that epic Halloween night when they spooked the Bubble Guppies, Franklin the Turtle, and all his friends—math powers activate!"

Everyone—Dora, Boots, Geo, Milli, and Bot—donned flowing ghost costumes, ethereal white fabric trailing like fog, eye holes glowing with friendly green light. The outfits rustled softly in the wind, mimicking the famous Halloween scare where Bubble Puppy and Mr. Owl had turned the tables on their friends. "I remember those Halloween nights so well, when Bubble Puppy and Mr. Owl floated around scaring everyone into giggles—it felt just like this, all fun and spooky!" "Perfect! Now let's float out and give those baddies the fright of their lives—boo power, times three!"

The ghost squad emerged moaning and gliding, sheets waving dramatically. Swiper, Maximo, Zeta, Angelica, Vicky, Candace, Rintoo, Minnie, pirate piggies, Plankton, Olivia, Kiki, Deema, Orange Blossom, Fancy Nancy, Vampirina, and Maggie and Miss Puff froze, then screamed wildly, eyes bulging like the Bubble Guppies and Franklin the Turtle's gang on those legendary Halloween nights. "Oh nooo! Real ghosts—swiping time's over, I'm outta here!" "Eeeeek! Not fair, I didn't sign up for this haunting—run, everybody, run for your lives!" They bolted in all directions, tails tucked and hats flying, vanishing into the dark woods.

Dora jumped with joy in the sheet remnants. "Yay! We did it, Boots and Geo—the ghosts scared them all away just like on those fun Halloween nights!" Rushing inside, she found her mom stirring cocoa in a sunny kitchen with checkered curtains and fresh-baked cookie scents. "Mom, you won't believe it! Swiper, Maximo, the shape bandit, Zeta, Angelica, Vicky, Candace, Rintoo, Minnie, pirate piggies, Plankton, Olivia, Kiki, Deema, Orange Blossom, Fancy Nancy, Vampirina, Maggie, and Miss Puff chased us, but with Geo's ghost costumes like Bubble Puppy and Mr. Owl's, we turned the tables and sent them screaming away!"
