Blue Chocolate Egg Trees are a type of garden tree that produces the homegrown fruit, Homegrown Blue Chocolate Eggs. They can be grown in a pet's front or back garden by purchasing the limited time Easter Egg Tree Seed at the Garden Shop and planting in a pet's garden. (Note: the Easter Egg Tree Seed randomly selects the color of the Chocolate Egg tree - there is an equal chance of getting a Blue Chocolate Egg Tree, a Pink Chocolate Egg Tree, or a White Chocolate Egg Tree.) These trees were introduced to the Facebook version of Pet Society on March 18, 2010.
