The squirrel can't believe its eyes when it crawls out of its tree one sleepy morning: Everything outside is white. No wonder, because it's winter and it snowed overnight. Snow? The squirrel has never heard of that before. But luckily, it has its best friend Bird, who shows it how much fun can be had with it. That's right, the squirrel thinks, a snowball fight is really great. But when it wakes up excited the next morning and looks forward to even more fun games in the snow, the white splendor is already gone. The squirrel is sure: A mischievous snow thief is at work here! Could it have stolen the beloved hazelnuts too?.
