Geo Umizoomi finishes his work at his desk, arranging his tools in neat patterns. His mind drifts to thoughts of puzzles and numbers, relishing the peaceful end of the day. The quiet is comforting, almost magical.

Geo Umizoomi freezes, his heart pounding. The figure lets out a low, howling sound as it swoops closer. "Ahhh! What is that?" he cries, dropping his ruler and sprinting toward the exit, his footsteps echoing.

Ms. Pattern[/@ch_2], stands near a table, arranging geometric blocks.] Ms. Pattern looks startled as Geo rushes in. "Ms. Pattern, I saw a ghost in the hallway! It was floating and making scary noises!" "A ghost, you say? Let’s go see together, Geo. I’m sure there’s an explanation," she replies, her voice calm and reassuring.

Geo Umizoomi clutches Ms. Pattern’s sleeve, his nerves still frayed. "Let’s follow these clues. It looks like someone’s been here recently," Ms. Pattern says, shining her light on the scraps.

Benny Blocks[/@ch_3], tangled in a sheet. Laughter echoes as Benny pulls off the white sheet, revealing his sheepish grin. A bucket of cleaning supplies sits beside him, and a stack of paper ghosts is scattered on the floor.] "Oh, Geo! I was trying out my costume for the Umi City Halloween Parade. I didn’t mean to scare anyone!" "See Geo, it was Benny all along—no real ghosts here," Ms. Pattern reassures. Relief washes over Geo as the tension fades.

"I guess even a math superhero can get scared sometimes," Geo admits, smiling. "Next time, I’ll warn you before I test my costume!" As laughter fills the room, Umi City’s night sparkles with camaraderie and fun.
