Milo the mouse found a giant cookie. It was bigger than his house. Milo’s eyes got big. “This is not a cookie,” he said. “This is a cookie mountain!” He took one bite. Crunch. He took another bite. Crunch. After ten bites, the cookie still looked huge. Milo smiled. “This is breakfast, lunch, dinner, and maybe next Tuesday.” He called his friends. Five mice came. They all ate. Crunch crunch crunch. The cookie was still big. Then Milo had an idea. “We can live inside it!” The mice made a tiny door. They made tiny windows. They made a tiny bedroom. That night, Milo slept inside the cookie. But in the morning, half the house was gone. “Who ate my wall?” he asked. His friend raised his hand. “I was hungry.” Milo sighed. “Okay. New rule. Do not eat the house while we are living in it.”
