Ruby splashed in the tub with Daddy, giggling as she squeezed their toy. "It’s so squishy and wobbly!" she laughed. Daddy grinned. "Careful, it’s tricky to control." Bloop! The balloon bounced out of the tub! "Come back!" Ruby cried as the balloon wibbled down the hall.

"Quick!" Daddy grabbed a towel. It wobbled out the front door and down the street. The balloon bounced into Kyra’s pool. Slurp! It swallowed Kyra mid-jump. "Help!" she giggled.

"We’re coming!" Ruby shouted, chasing after it. At the play center, Octav slid down a green slide when—slurp!—he vanished into the balloon. "Don’t worry, Octav!" Ruby called. The balloon wobbled to Ruby’s school, swallowing Georgie on the playground. "This is serious!" Daddy said, running faster.

At Uncle Jake and Aunty Georgia’s, the balloon scooped them up too. "Hang tight!" Ruby called. The balloon rolled to Ruby’s house, where it swallowed Mummy and baby Lucas. "Mummy! Lucas!" Ruby yelled, determined to stop it. The balloon grew enormous, wobbling across the sky.
