 Tommy is white, bald, and toothless (with the exception of "Weaning Tommy", in which he begins teething) and is most commonly seen wearing a light blue t-shirt and diaper with no shoes, unlike the other babies, who are typically fully dressed.As he is an infant, Tommy is often seen crawling but he is able to walk, albeit somewhat unsteadily and pigeon toed, and uses his diaper as a pocket, keeping his screwdriver in there among other things.Tommy is a brave child, with a strong sense of justice, always eager for an adventure and unafraid to stand up for what is right.
