Monster Update: 40

It's hard to say for sure how big the Tummy Monster will be, but the average newborn weighs about 7.5 pounds (a small pumpkin (pictured)) and is about 20 inches long. The biggest part of the Monster's body is his head, but his still-pliable skull will give it the flexibility necessary to squeeze through the birth canal. If and when he deigns to make an appearance, that is.
