Tommy's First Birthday
The day rolls on and Betty and Howard DeVille arrive for the party with their twins, Phil and Lil, and Chuckie Finster, the neighbors son. When they're all gathered in the playpen, Tommy tells them about the dog food commercial, and his belief that if they eat dog food, they'll turn into dogs. The other babies find this appealing and decide they want to be dogs, too. But before they can leave the playpen, the grownups put party hats on the babies and snap pictures, though the babies aren't thrilled by either one.
