Three bears went out of their house, and a naughty little girl pushed open the door and went in. Father bear's porridge was hot, mother bear's was cold, but baby bear's was just right and she ate it. Father bear's chair was high, mother bear's was low, but baby bear's was just right. She sat on it and broke it. Father bear's bed was hard, mother bear's was soft, but baby bear's was just right and she went to sleep. What happened next?
