You take a deep breath and decide to chase the fox. "Hey! Come back!" you call. The snow fox looks at you with wide blue eyes—then zoom! He dashes away between the peppermint trees. You run after him. Your boots sink into the soft snow. Your breath comes out in little puffs of fog. The fox is fast. Really fast. But as he leaps over a snow-covered log, the paper in his mouth slips loose. It flutters to the ground. You scoop it up. "Yes! I got it!" You hurry back to Santa's Village as the sky turns pink with sunset. Snowflakes fall gently on your shoulders as you run into the workshop. "Santa! I found the other half!" you say proudly. Santa takes the paper, but then his smile slips just a little. "Oh dear…" he says softly.
