Monster Update: 25

Head to heels, the Tummy Monster now measures about 13.5 inches. His weight — a pound and a half — doesn't sound like much, but he's beginning to exchange his long, lean look for a more rounded one. As the Monster gains weight, his wrinkled skin will begin to smooth out and he'll start to look more like a mini newborn. His hair is probably recognizable now in color and texture, although both will likely change after he's born.
