Answer: Baby-Face
Step-by-step explanation:
Based on the description provided, the Olmec figurine is most likely a "baby-face" figurine. These figurines were small and had chubby bodies with large heads, often resembling babies or young children. They were believed to be associated with fertility and nurturing. The other options - transformation, elongated, and were-jaguar - are all different types of Olmec figurines, but they do not match the description given.
