Snowy peaks in the distance

The days are shorter, the trees lost their leaves and the first snow starts to fall. It is winter! That's when the mouse sees them for the first time: tall, white peaks. They must be the mountains, where the river originates! The squirrel is fascinated by them as well, they look like teeth! So while the other animals are preparing themselves for the winter months ahead, the mouse and squirrel prepare their sleigh to go see the snowy peaks for themselves. But the more they approach.. the taller they get! The two friends manage to finally reach the highest top and can look down on the forest they call their home. Satisfied, they want to head home, and decide to simply slide down. But slide on the wrong side of the mountain! Where will they land?
