Edmund is a little on the plump side and Terry is a bit of a rake. When they discover the countries under the Earth they are divided and sent to the warring kingdoms of the Fattypuffs and the Thinifers. The Fattypuffs eat six square meals a day with light snacks in between. The Thinifers like nothing more than discipline and work six days a week.
