Meet mr. little guy, the inspiration for Lylian, Lost Land of the Lytles.

For over 20 years, people of all ages have been leaving notes on the shore of Lake Harriet, behind a wee door in the hollow of a tree for and elf named mr. little guy. And for 20 years their notes have been answered. Each year 1,500 to 2,000 people write to say hello, seek advice and ask for their wishes to come true. Every letter ends with "i believe in you."
