Mischievous elf's mission for A child: book tour

A Christmas elf, also known as a mischievous elf, presents a mission to a child: they must build a tall tower with books they have already read. They then need to take a photo of the book tower and send it to the North Pole. The mission should be personalised with the child's name before printing. For added realism, it is possible to pretend to send the photo to an email address like booktower@northpole.com. This "elf" mission encourages children to read.
