An unusually-shaped vegetable is a vegetable or fruit that has grown into an unusual shape not in line with the normal body plan. While some examples are just oddly-shaped, others are heralded for their amusing appearance, often representing a body part such as the buttocks. Pareidolia can be common in vegetables, with some people reporting the appearance of religious imagery.
A giant vegetable is one that has grown to an unusually large size, usually by design. Most of these maintain the proportions of the vegetable but are just larger in size.
