Kiki, the energetic guitarist, strums a bouncy tune while Twist taps along on the drums. Shout and Marina laugh as they rehearse a new song, their voices echoing with excitement. Suddenly, a chilly gust sweeps through the room, flickering the lights.

Milli and Bot, friends from Team Umizoomi, peek into the room just as the ghostly figure swoops past, howling softly. The Bubble Guppies—Molly, Gil, and Deema—slide in, eyes wide with fear. "Did you see that? There’s a ghost in here!"

Kiki clutches her guitar as she runs, while Shout yells, "Run for your lives! It’s after us!" The Bubble Guppies tumble over each other, diving behind a water fountain. Milli grabs Marina's hand, leading her toward the safety of the music room.

Geo Umizoomi[/@ch_10] is busy plotting out a new adventure. The friends burst in, breathless and frantic.] Molly explains, "Geo, you have to help us! There’s a ghost!" Geo Umizoomi stands tall, tapping his helmet thoughtfully. "Don’t worry, team! Let’s solve this mystery with shapes and logic!"

He follows a trail of sparkly dust to a storage closet, where the ‘ghost’ is hiding behind a white sheet.] With a gentle tug, Geo Umizoomi pulls away the sheet, revealing Little Bill, giggling with a flashlight and a homemade costume. "Surprise! I just wanted to play a spooky trick!" The friends burst into relieved laughter.

Little Bill[/@ch_11], now sheepishly smiling.] "That was the best trick ever, Bill, but next time maybe warn us first!" Deema jokes, "At least we know we run fast!" The Fresh Beat Band, Team Umizoomi, and the Bubble Guppies share a happy song, celebrating their bravery and friendship.
