From a very early age, humans tend to be fascinated by food that comes in the form of unexpected shapes. McDonald's chicken McNuggets are no exception as they come in four purposely designed unique shapes, but fans of the nuggets may not know the reason why they are shaped like that.

The McNuggets' four non-distinct shapes resemble a ball, a bell, a boot, and a bone. After the chicken meat is pressed into these shapes by way of machinery, it is given two layers of batter that can slightly obscure the nuggets' intended form.

The McNuggets’ consistent shapes are made to appeal to children and to ensure that the nuggets are always cooked to perfection. McDonald's Canada stated that the nuggets come in four shapes because, "Three would've been too few; five would've been, like, wacky."
