Santas Elf Pets are adorable little animals sent straight from the North Pole. These cuddly pets stay all year round with the children who adopt them, and can be hugged, cuddled and played with. Every Christmas, the Elf Pets help Father Christmas with all his chores, and children who have them can also help to send him the magic he needs to make his sleigh fly and deliver the presents on time. All Elf Pets come with their own hardcover storybook, which explains exactly what they do to help Santa.
