Tommy is disgruntled at a comment Angelica makes at a breakfast about the dinosaurs being extinct and expresses his concern to the other babies of the possibility of Reptar being extinct too. After an accidental suggestion by Chuckie's that he's "hiding," the babies look for him in the backyard and discover a lizard which looks exactly like him and come to assumption that it is Reptar's child. To keep him in a secret from the grown-ups, Tommy hides the lizard inside his diaper and the lizard crawls around inside Tommy’s diaper causing him to twitch and squirm a lot while the babies ponder what to do with Reptar's Baby. A commercial for "Reptar on Ice" suddenly plays, to the shock of the babies and Stu decides to take them all. The babies are now thrilled because they can now "return" the lizard to its "father".
