In the wild, pigs are foraging animals, primarily eating leaves, grasses, roots, fruits, and flowers. In your kitchen, pigs are much pickier. Due to their extreme cuteness (I mean, just look at this little guy), pigs are always served the finest of cuisine, eggs. Egg yolks to be precise. Their preference for yolks is so strong that they will separate an egg from its yolk with ease.
Curly tail definitely included.
