In Monster Mathland, 00000 and Uno overheard a rumor. "Some monsters are being mean, hoarding all the number berries!" said a two-headed creature named Toodles. They decided to investigate, and soon they met a grumpy monster named Negative Nine, growling over his berry pile. But instead of running away, Uno approached gently. "Why all the berries, Negative Nine?" he asked. Negative Nine grumbled, "I want more than zero!" But 00000 smiled. "In Monster Mathland, we share so everyone has fun!" With Uno's help, they showed Negative Nine how sharing made playing games like berry toss even better. Negative Nine's frown turned upside down, and soon, he was passing berries to everyone, laughing as the piles turned into shared mountains of joy.
