Kutzer points out Timmy and his wife wear clothes, but the other squirrels and the bear do not. There is no apparent reason for this differentiation. She admits that this may be Potter's attempt to separate her anthropomorphized animals from her natural ones, but she believes the attempt fails on both narrative and artistic grounds. Logically, she argues, all the squirrels should wear (or not wear) clothes because they all live and behave in a natural manner: Timmy and Goody inhabit a nest in a tree (not a comfortable little house somewhere), and all the squirrels gather nuts for the coming winter. Except for Timmy having a wife, there is no clear distinction between natural and personified squirrel nature. In another stumbling block to logic, Timmy's red jacket appears then disappears then reappears in the illustrations with no basis either in the plot or Timmy's character, but apparently in Potter's personal need for a splash of colour here and there. In this case, Potter has allowed an external force to shape the tale rather than letting the tale find its own shape.
