Squirrel couldn't believe his eyes when he sleepily crept out of his tree one morning: everything outside was white. No wonder, since it was winter and it had snowed overnight. Snow? Squirrel had never even heard of it. But luckily, he had his best friend, Bird, who showed him how much fun it could be. "That's right," thought Squirrel, "a snowball fight is really great." But when he woke up the next morning, excited and looking forward to even more fun games in the snow, the white splendor was already gone. Squirrel was sure of one thing: a cheeky snow thief was up to no good! Had he stolen his beloved hazelnuts too?
