This is the greatest...He just appeared one day at my house.  My kids noticed right away (he was sitting high on a shelf).  Then we found the book, and read it all.  We named him "Jangels", they were soooo into this!  Every morning they could wait to do all thier chores and then hurry to find the elf.  It was great fun, and they were EXTRA GOOD becuase our Elf was watching all the time! And on Christmas Eve before he flew back to Santa they all said goodbye to him, sooo cute!! We got the activity book too, this would be great for any family or classroom!  Really, really loved this, great tradition!!!
