A Blueberry Pie was once available in Adopt Me! and could be bought from Green Groceries. It featured a beige crust, lattice toppings, and a blueberry filling that made it look similar to waffles, albeit not as fluffy.
Being a food item, it served to fulfill the 'Hunger' task of a baby or pet up to five times. After the Farm Shop was released, however, this item became rare and could only be obtained through trading. The Raspberry Pie is its counterpart - another food item that can satisfy one's cravings.
