Leap Year dragons are on of my personal favorites, just because I think they look cool! :)
Here are the best combinations to get a Leap Year Dragon:
Love + Panlong
Lichen + Magnetic
Flower + Love
The incubation time is 14 and a 1/2 hours.
The exceptionally rare leap year dragon can only be seen in the wild once every four years near Bridget's Pass. Getting one of these in your park is sure to make your visitors over the rainbow! Or is it over the moon? I can never remember...
