Monster Update: 19

The Tummy Monster weighs about 8 1/2 ounces, and it measures 6 inches, head to bottom — about the length of a small zucchini (pictured). Its arms and legs are in the right proportions to each other and the rest of it's little body now. The Monster's kidneys continue to make urine, and the hair on its scalp is sprouting. This is a crucial time for sensory development: the Monster's brain is designating specialized areas for smell, taste, hearing, vision, and touch.
